Question

solve the equation -9(3z - 4) = -35 + 2z​

Answer 1

Answer:

z = 71/29 ( = 2.45)

Step-by-step explanation:

-9(3z - 4) = -35 + 2z​   (by PEDMAS, expand parentheses first by distributive property)

3z(-9) - 4(-9) = -35 + 2z​

-27z + 36 = -35 + 2z​   (add -27z to both sides)

36 = -35 + 2z + 27z

36 = -35 +  29z   (add 35 to both sides and rearrange)

29z = 36 + 35

29z = 71

z = 71/29 ( = 2.45)
