Exercise 18 Page 475

Start by using the Subtraction Property of Equality.

d=8

Practice makes perfect

To solve an equation, we should isolate the variable term. In this case, we will use the Subtraction Property of Equality and Division Property of Equality.

5 + 4d = 37

LHS-5=RHS-5

5 + 4d - 5 = 37 - 5

Subtract terms

4d = 32

.LHS /4.=.RHS /4.

4d/4 = 32/4

Calculate quotient

d = 8

The solution to the equation is d=8. We can check our solution by substituting it into the original equation.

5 + 4d = 37

d= 8

5 + 4( 8) ? = 37

Multiply

5 + 32 ? = 37

Add terms

37 = 37 ✓

Since the left-hand side is equal to the right-hand side, our solution is correct.
