✔ 最佳答案

2(z-3)=5-3z
so
2z - 6 = 5 - 3z
so
5z = 11
so
z = 11/5 = 2.2

multiply out the brackets
2z - 6 = 5 - 3z
2z +3z = 5 +6
5z = 11
z= 11/5
z= 2.2

2 z - 6 = 5 - 3 z
5 z = 11
z = 11 / 5

2(z - 3) = 5 - 3z
2*z - 2*3 = 5 - 3z
2z - 6 = 5 - 3z
2z + 3z = 5 + 6
5z = 11
z = 11/5 (2.2)

2z -6=5-3z
5z=5+6
5z=11
z=11/5

Lyndsey - it seems to me that you have not been paying enough attention during your lessons.
