Problem A

What is the value of x in the following equation?

5 (4x + 1) – 3 (5x – 6) = 38

Problem A

What is the value of x in the following equation?

5 (4x + 1) – 3 (5x – 6) = 38

( )1+4x5 ( )65x3 –– = 38

5+20x 1815x– = 38+

235x = 38+

5x = 15

x =3 Divide each side by 5.

Write original equation.

Distributive property

Combine like terms.

Subtract 23 from each side.

ANSWER

Problem B
