Algebraic equations x + 20 = 100

Question

Algebraic equations

`x + 20 = 100`

Answer 1

x = 80

Explanation:

The whole reason algebra exists is to solve for a variable. Therefore, the only way to get x by itself or to see what x equals is to subtract 20 from both sides. Doing this will make x be all alone on one side of the equation and to see what x is.

x + 20 = 100

x + 20 -20 = 100 -20

x = 80
