Solve this equation: 5x-4=3x+7
Step 1
Collect x terms on one side (here we subtract 3x from both sides to give 2x on the left, and 0x, on the right)
Step 2
Collect the non x terms on theother side (here we add 4 to both sides to give 0 on the left and 13 on the right
Step 3
We have the value of 2x = 13. We want the value of just x. Divide both sides by 2 to get x = 13/2 or 6.5
