4(7a + 5) = -160

mutiply the bracket by 4

(4)(7a)(4)(+5)= -160

28a+20= -160

move +20 to the other side

sign changes from +20 to -20.

28a+20-20= -160-20

28a= -180

Divide by 28

28a/28= -180/28

x= -180/28

reduce by dividing 4

-180/4= -45

28/4= 7

-45/7 or -6 3/7

Answer : x= -45/7 , x= -6 3/7
