Answer 3

OK thanks you guys!!

Answer 4

sorry ikram try again

Answer 5

if you are solving a system of equations, you will see the first equation becomes
2a - 12 = 9
and the 2nd equation is
2a -36 = 11

Answer 6

you can simplify both equations. add +12 to both sides of the 1st equation
2a-12+12= 9+12
2a = 21

add +36 to both sides of the 2nd equation
2a-36+36= 11+36
2a= 47

the first equation says 2 times a is 21
the 2nd equation says 2 times a is 47

what a works for both ?

Answer 7

those 2 a's are not equal to each other????
