Answer:
b. The solutions are the same. It means that the equations have identical solutions.
c. 4x+ 6= 28 ( I have subtracted 4 from each side)
8x+ 20= 64 ( In this case, multiplied by 2 on both sides)
2x+ 5= 16 ( divided by 2 on both sides)
d. 4x+10= 32
4x+ 10- 10= 32- 10 (subtracted 10 on both sides)
4x= 22
x= 22÷4 ( divided by 4 on each side)
x= 5.5
