Question

3 (5z – 7) +2 (9z – 11) = 4 (8z – 7) – 111 Solve the equation

Answer 1

Answer

Step-by-step explanation:

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

15z+18z-32z=-29-111+21+22

33z-32z=-139+43

z=-96

Answer 2

Answer:

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

Step-by-step explanation:

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

To find : Solve the equation ?

Solution :

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

Multiply the terms,

$15z -21 +18z-22=32z-28-111$

$15z+18z-32z=-28-111+21+22$

$33z-32z=-139+43$

$z=-96$

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