Question

Solve: 5(x − 1) = 3(x + 2) − 7

Answer 1

5(x - 1) = 3(x + 2) - 7
5x - 5 = 3x + 6 - 7
2x = 11 - 7
2x = 4
x = 2

Answer 2

They aren't? 5(x-1) = 5x - 5. 3(x + 2) = 3x + 6. Moving all the x values to the left and all the numerical values to the right gives 5x - 3x = 6 + 5 - 7. Thus 2x = 11 - 7
therefore 2x = 4
Therefore x = 2.

Answer 3

5x-5=3x+6-7
5x-3x=6-7+5
2x = 11 - 7
2x=4
x=4/2
x=2

Sorry bloody typo :P

Answer 4

Hahaha - Yes, I know those ;)
