What is the first step?

• 7(2y - 4) - 2y = 5

• 7x - 2(2x - 4) = 5

• 7(2x - 4) - 2y = 5

• 7x - 2y = 2x - 4

• No solution

What is the first step?

• x = 6(8x + 1) + 3

• y = 8(6x + 3) + 1

• y = 6(8x + 1) + 3

• 8x + 1 = 6x + 3

• x = 8(6x + 3) + 1

x = -3y - 13

4x + 2y = 4

What is the first step?

• 4(-3y - 13) + 2y = 4

• 4(-3x - 13) + 2y = 4

• 4x + 2(-3y - 13) = 4

• 4x + 2(-3x - 13) = 4

• -3y - 13 = 4x + 2y
