Question 161309
2x - 1 = 4x + 3


Let's subtract 4x + 3 from both sides...

2x - 1 - (4x + 3) = 4x + 3 - (4x + 3)


Remember to distribute your negatives!

2x - 1 - 4x - 3 = 0


Combine like terms...

(2x - 4x) -1 - 3 = 0
-2x - 4 = 0

Add 4 to both sides


-2x - 4 + 4 = 0 + 4
-2x = 4

Divide both sides by -2

x = 4/-2
x = -2


Therefore, you did it correctly...congratulations :)
