What is the first step to solve the equation 20 = 2 - a?

Back

The first step is to isolate 'a' by subtracting 2 from both sides, resulting in 18 = -a.

Front

Solve for a: 20 = 2 - a

Back

a = -18

Solve for x: -4x + 1 = 21

Back

x = -5

What is the process to solve the equation 3 + (1/4)a = 31?

Back

First, subtract 3 from both sides, then multiply by 4 to isolate 'a'.

Front

Solve for a: 3 + (1/4)a = 31

Back

a = 112
