How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform inverse operations in the reverse order of operations.

Front

Solve for n: 3n + 4 = 7

Back

n = 1

Front

Solve for s: 9 = 2s + 1

Back

s = 4

Front

Solve for v: 8 = 4v + 12

Back

v = -1

Front

Solve for m: -5 = 3m - 14

Back

m = 3

Front

Solve for c: 4c - 6 = 2

Back

c = 2

Front

What is the first step in solving the equation 3n + 4 = 7?

Back

Subtract 4 from both sides to get 3n = 3.

Front

What is the second step in solving the equation 3n = 3?

Back

Divide both sides by 3 to find n = 1.
