Answer 1

Explanation:

2(4z+3+3z)=174

7z+3=174/2=87

7z=87-3=84

z=84/7=12

WX=3z=3×12=36 units

Answer 2

36 units

Explanation:

`2(4z + 3 + 3z) = 174 \\ \\ (7z + 3) = (174)/(3) \\ \\ 7z + 3 = 87 \\ \\ 7z = 87 - 3 \\ \\ 7z = 84 \\ \\ z = (84)/(7) \\ \\ z = 12 \: \\ \\ WX = 3z \\ \\ WX \: 3 * 12 \\ \\ WX = 36\: units`
