Exercise 60 Page 108

Gather all of the variable terms on one side of the equation and all of the constant terms on the other side.

a=5

Practice makes perfect

To solve an equation, we should first gather all of the variable terms on one side and all of the constant terms on the other side using the Properties of Equality.

-2a+5a-4=11

Add terms

3a-4=11

LHS+4=RHS+4

3a-4+4=11+4

Add terms

3a=15

.LHS /3.=.RHS /3.

3a/3=15/3

Calculate quotient

a=5

The solution to the equation is a=5.
