Question

simplify and solve 2(5z – 7) – 2(8z – 11) = 4(5z – 13) – 17​

Answer 1

Step-by-step explanation:

2(5z - 7) - 2(8z - 11) = 4(5z - 13) -17

10z-14-16z+22 = 20z-52-17

10z-16z-20z = -52-17+14-22

-26z = -69-8

-26z = -77

z = -77/-26 = 77/26 = 2 25/26

Answer 2

Answer:

z=  77/26

Step-by-step explanation:

2(5z−7)−2(8z−11)=4(5z−13)−17

(2)(5z)+(2)(−7)+(−2)(8z)+(−2)(−11)=(4)(5z)+(4)(−13)+−17(Distribute)

10z+−14+−16z+22=20z+−52+−17

(10z+−16z)+(−14+22)=(20z)+(−52+−17)
