Solve: 2x + 2 = 18
x = 8
Algebra: What is the reciprocal operation of q x 2
q / 2
Prove that x = 4 for the following expression:
2x - 2 = 6
2(4) - 2 = 6
8-2 = 6
6 = 6 :)
Turn the following sentence into an equation:
Three groups of 4 is 25 less than two times a number
3(4) = 2x - 25
OR
3(4) = -25 +2x
25 is 20 less than one fifth of a number
25 = 1/5x - 20
Solve: 3x + 4 = 7
x = 1
simplify: 3(2w - 3) + w
7w - 9

Timmy goes to Stampede and pays $35 to enter and $5 per ride. If he spends $115 in total, how many rides did he go on?
CREATE AN EXPRESSION TO REPRESENT THIS, YOU DO NOT HAVE TO SOLVE IT (YET)
$35 + 5x = 115
Algebra: A school spends $120 on gym decorations after using a $50 coupon. If each decoration costs $10, how many decorations did they buy?
Algebra: 17
Solve: 3x + 3 - 2x = 21
x = 18
x - 7 = -21
x = -14
Solve: (3x-5)4 = 4
x = 2

Simplify
2(2 + 3x) - 3(7 - 4x)
18x - 17
Solve: 4x - 5 - 3x + 2 - 2x = 9
x = -12
Simplify:
17 + 2x - 3a +2 - 3x - 4a
19 - x - 7a
OR
-7a - x + 19
Simplify: -4(3x - 2) -2(4 + 3x)
-18x
Simplify: 22p - 7p + 19 - 15 - 12
15p - 8
Simplify: -(x + 7) -2(4x + 1)
-9x -9
Solve: 21 = x - 12
x = 33
Distribute and solve
-9 (-3x -7) = 117
Algebra: x = 2
simplify: 4h - 4k + 2k + 7h - 3k - 3
11h -5k - 3
Write an equation for the following sentence:
One hundred and eleven is 21 more than three times a number.
111 = 21 +3x
Simplify: 4(-4 + 2x) - 2(20x - 15)
-32x + 14
