Question

3z+7by 9=2by8 please answer it fast

​

Answer 1

Answer :

(2z−7)−3(3z+8)=4z−9

(2z−7)−(9z+24)=4z−9

(2z−7)−9z−24=4z−9

2z−7−9z−24=4z−9

2z−9z−4z=−9+7+24

2z−9z−4z=−2+24

−11z=22

z=

11

22

z=−2

To check this

Putz=−2

(2(−2)−7)−3(3(−2)+8)=4(−2)+−9

(−4−7)−3(−6+8)=−8−9

−11−3(2)=−17

−17=−17
