Question

Solve the equation 3x -7 = 5x +19

Answer 1

The first thing you want to do is combine like terms. This means you should have all the x's on one side and the constants (numbers) on the other side. You can subtract 5x from both sides of the equation and then add 7 to both sides. This gives you -2x=26. Divide both sides be -2 to isolate the variable and your answer is x=-13. Hope this helped!

Answer 2

3x -7 = 5x + 19
subtract 19 to both sides 
3x -2 = 5x
subtrct 3x from both sides
-2=2x
divide two by both sides
-1 = x
