Exercise 12 Page 9

Isolate a using inverse operations.

a = 51

Practice makes perfect

To solve the equation, we need to isolate a using inverse operations and the Properties of the Equality.

15 = a/3 - 2

LHS+2=RHS+2

15 + 2 = a/3 - 2 + 2

Add terms

17 = a/3

LHS * 3=RHS* 3

17 * 3 = a/3 * 3

FracMultDenomToNumber

a/3* 3 = a

17 * 3 = a

Multiply

51 = a

Rearrange equation

a = 51
