1/2 (6x - 4) = 4x - 9

What's x?

x = 7

Step-by-step explanation:

1) distribute (1/2) into (6x - 4)

end up with: 3x - 2 = 4x - 9

2) add 9 to both sides of the equation to cancel out - 9

end up with: 3x + 7 = 4x

3) divide both sides of the equation by 4 to cancel out the 4 on the right side

end up with: (3/4) x + 1.75 = x

4) subtract (3/4) x from both sides to cancel out + (3/4) x

end up with: 1.75 = (1/4) x

5) multiply both sides by 4 to cancel out (1/4)

end up with: x = 7
