Use distribution to multiply (7a+5) by -4 to get -28a - 20
The solution is a = 5
Check the solution by evaluating the original expression -4(7a+5) to verify that it equals -160
undo subtract 20 by adding 20 to both sides of the equations to get -28a = -140
undo multiplying by -28 by dividing by both sides of the equation by -28 to get a = 5
