equ1. Solve each completely showing pencil and paper work.: a.) 4x = -12; b.) 4 + x = -12; c.) x - 4 = -12; d.) x/4 = -12

equ2. Solve each completely showing pencil and paper work.: a.) 5x + 3 = -3x + 5; b.) 8x - 6 + 2x = 8x - 3; c.) 4x - 5x + 3(2x -1) + 1 = 0; d.) 8x - 6 = 7x - 6

equ2a. Solve each completely showing pencil and paper work.: a.) -.4x = -12; b.) -4 - x = -12; c.) 3x - (2x + 4) = -12; d.) 3x/4 = -12

equ3. Solve each completely showing pencil and paper work.: a.) 3(x + 1) - 2x = -1; b.) 3(x + 1) -2x = 3 + x; c.) 3(x + 1) - 2x = 4 + x

equ3a. Solve each completely showing pencil and paper work.: a.) 2x + 3(x- 6) = 4(x+1); b.) -4 + 3x = -12 + 5x; c.) 2x - 4 = 2(x-2) + 4; d.) -2x/3 + 4/5= 1/4

Bright & Shiny. In order, connect the dot from one answer: to the dot for the next answer. Solve each equation. Show work for full credit.; 1. 3x + 5 = 3x -1; 2. .5x +.5x +.5x +.5x = 4; 3. 3x + 4 = 2; 4. 4x - 1= 5x + 3; 5. 4x + 2( x - 1) = 3(2x + 3) - 11; 6. 4x + 7 = 2(x + 3) +2x - 1

equ4. List, based on the equations in question equ1. - equ3.: & Bright & Shiny, the kinds of solutions which are possible when solving linear equations. Explain the reason for each solution. [Hint: What does it mean to SOLVE an equation?]

equ5. Write the "semiequation" and then the equation, and: then the work necessary to solve each.; a.) The sum of 3 and 5 times a number is the same as double the sum of the number and 1.; b.) There are two consecutive even integers such that the sum of the smaller and triple the larger is 86. Find these integers.

equ6. Complete: The only difference between: solving an equation and an inequality is ..."

equ7.: The interval notations [a,b], [a,b), (a,b), and (a,b] each have different meaning because of the meaning of the (, ), [, or ] which indicate the inclusion or exclusion of the endpoints of the interval. Use the endpoints 2 and 6. Write notes in words and with a number line to illustrate each of the four intervals; 1st: State interval using the interval notation.; 2nd: Draw a number line indicating the interval.; 3rd: Describe the interval in English.

equ8. Write the "semiequation" and then the equation, and: then the work necessary to solve the problem.; What grade is needed on the last of 4 tests to earn a grade of 80 or better if a student has grades of 90, 65, and 89?
