Question

3(5z+7)+2(9z−11)=4(8z−7)−111 ​

Answer 1

The solution of the expression is z=-96z=−96

Step-by-step explanation:

Given : Equation 3 (5z -7) +2 (9z- 11) = 4 (8z-7)-1113(5z−7)+2(9z−11)=4(8z−7)−111

To find : Solve the equation ?

Solution :

Equation 3 (5z -7) +2 (9z- 11)= 4 (8z-7)-1113(5z−7)+2(9z−11)=4(8z−7)−111

Multiply the terms,

15z -21 +18z-22=32z-28-11115z−21+18z−22=32z−28−111

15z+18z-32z=-28-111+21+2215z+18z−32z=−28−111+21+22

33z-32z=-139+4333z−32z=−139+43

z=-96z=−96

Therefore, The solution of the expression is z=-96z=−96

Answer 2

Step-by-step explanation:

3(5z+7)+2(9z-11)

=3x5z+7x3 +2x9z-2x111

=15x+21 + 18z-22

=15x+18z+22-21

=33z+1=4(8z-7)-111

33z+1=32z-28-111

33z+1=32z-83

33z-32z=-83-1

1z=82

z=82/1

z=82

the final answer is 82

i am not sure about the answer
