Question

What is the value of X if 3/2x +4 =2x-1

Answer 1

Let's isolate x by moving the -1 to the left and the 3/2x to the right (direction chosen so that you don't get negative numbers):


`4 + 1 = 2x - (3)/(2)x \implies 5 = (1)/(2)x`

Now multiply both sides by 2 and swap sides:


`2 \cdot 5 = 2 \cdot (1)/(2)x \implies x = 10`
