Question

10. 11. 15(x - 1)+4 (x + 3) = 2 (7 + x) 12. 3 (52 - 7) 42 (92 - 11) = 4 (8z - 7) -- 111 13. 8(x - 3) - (6 - 2x) - 2 (x+2) - 5 (5 - x) 14. 3 (n - 4)+ 2 (4n - 5) = 5 (n + 2) + 16​

Answer 1

Step-by-step explanation:

3(5z−7)+2(9z−11)=4(8z−7)−111

15z−21+18z−22=32z−28−111

33z−43=32z−139

z=−96
