Exercise 45 Page 259

Distribute 2, then continue solving the equation.

x=4

Practice makes perfect

On the left side of the equation, we have a product that can be simplified using the Distributive Property.

2(x-5)=2-x

Distribute 2

2x-10=2-x

Now, we can continue to solve using the Properties of Equality.

2x-10=2-x

LHS+x=RHS+x

2x-10+x=2-x+x

Add terms

3x-10=2

LHS+10=RHS+10

3x-10+10=2+10

Add terms

3x=12

.LHS /3.=.RHS /3.

3x/3=12/3

Calculate quotient

x=4
