Solve Equations By Adding or Subtracting Practice

Answer 1

Sure! Here are a few practice equations for you to solve by adding or subtracting:

1) 3x + 5 = 17

First, subtract 5 from both sides:
3x + 5 - 5 = 17 - 5
3x = 12

Then, divide both sides by 3 to solve for x:
3x / 3 = 12 / 3
x = 4

So the solution to the equation is x = 4.

2) 2y - 6 = 10

First, add 6 to both sides:
2y - 6 + 6 = 10 + 6
2y = 16

Then, divide both sides by 2 to solve for y:
2y / 2 = 16 / 2
y = 8

So the solution to the equation is y = 8.

3) 4z - 9 = 7

First, add 9 to both sides:
4z - 9 + 9 = 7 + 9
4z = 16

Then, divide both sides by 4 to solve for z:
4z / 4 = 16 / 4
z = 4

So the solution to the equation is z = 4.

I hope this helps! Let me know if you have any other questions.
