Find the value of b.

Answer explanation

Set up an equation.

-2b+60 = 3b + 45

Add 2b on both sides

60 = 5b + 45

Isolate the variable and solve the two-step equation for a.

CCSS.7.G.B.5

Find the value of b.

Answer explanation

Set up an equation.

160 - 7b = 3b + 130

Add 7b on both sides

160 = 10b + 130

Solve the two-step equation. Isolate the variable by using inverse operations.

Subtract 130 on both sides.

Then divide both sides by 10

Find the value of a.

Answer explanation

Set up an equation.

67 - 13a = 51 - 5a

Add 13a on both sides

Subtract 51 on both sides

67-51 = -5a + 13a

Combine like terms and then solve for a.
