✔ 最佳答案
Distribute the -5 to get (-15+45)+4=5x-11.. Then add the eleven to isolate the variable. and you get (-15+45)+4+11=5x now simplify the left side of the equation to get 45=5x and divide by 5 to get x=9.

-5(3-9) + 4 = 5x - 11
-5(-6) + 4 = 5x - 11
30 + 4 = 5x - 11
34 = 5x - 11
34 + 11 = 5x
45 = 5x
45/5 = x
9 = x
x = 9
-5(-6) + 4 = 5x - 11
30 + 4 = 5x - 11
34 = 5x - 11
34 + 11 = 5x
45 = 5x
45/5 = x
9 = x
x = 9

5x - 11 = - 5(3 - 9) + 4
5x - 11 = - 5(- 6) + 4
5x - 11 = 30 + 4
5x - 11 = 34
5x = 45
x = 9.
5x - 11 = - 5(- 6) + 4
5x - 11 = 30 + 4
5x - 11 = 34
5x = 45
x = 9.
