Solve the following equation: 3x - 5 = 10 + 7x.
umka21 [38]

When solving equations like these, our number one goal is to get x to be alone.

So given the equation lets go through it step by step.

3x - 5 = 10 + 7x  (first step is to add 5 to both sides)

    + 5 = + 5    ( Now lets see what we have now)

3x = 15 + 7x ( We need the x to be alone! So lets subtract -7x from both sides.)

-7x =       -7x   ( now what do we have?)

-4x = 15  (okay divide both sides by 4 to isolate the x)

÷4 = ÷4   (now the 4's on the left side cancel out, and we solve on the right side)

x = 3.75

That's your answer :) Good Luck!
