3x + -1 = 5x + 4
Either Subtract 3x from both sides or Subtract 5x from both sides. rewrite as -2x + -1 = 4 OR -1 = 2x + 4

What is the first step to solve this? Rewrite after you simplfy. 3x + 5x + 2 = 6x - 1
Simplify. Add 3x + 5x and make it 8x 8x + 2 = 6x - 1

Solve for x: 4x + 3 = -6x + -47
x = -5

Solve for y: 3y+ 6 = -2y + 9.75
y = 3/4 or .75

Solve for x: -5x - 6 = -36
x = 6

What is the first step? Rewrite after you simplify. 3(x - 1) = 4x
Use the distributive property. 3(x - 1) = 3*x + 3*-1 = 3x +-3 3x + -3 = 4x

Solve for x: 2(x + 1) = 5x + 11
x = -3

Solve for y: 5(y + 6) = 9y + 10
y = 5
300
Solve for t: -t + 18 = -6t - 7
t = -5

Solve for g: 5 = 3 - 6x
x = -1/3 or -0.3 (the 3 repeats)

What is the first step? Do the first step, then rewrite the equation. -5x = -8x - 4
Either add 5x to both sides, or add 8x to both sides. Acceptable answers: either 0 = -3x +-4 or 3x = -4

Solve for x: -3 - 4x = 21- 8x
x = 6

Solve for y: -7y + -2y + 8 = 48 + y
y = -4

Solve for d: 4(3d + 4) = 2d - 4
d = -2

Solve for c: 5 - 4c = 7c + 8
c = -3/11 or -0.27272727272727272727 (repeating)

What is the first step? Do the first step, and then rewrite the equation. -8x + 3(4x +7) = -7x
Use the distributive property. 3(4x + 7) = 3*4x + 3*7 = 12x + 21, so -8x + 12x + 21 = -7x
500
Solve for x: 2x + 4(3x - 2) = 11x + 1
x = 3
