✔ 最佳答案
You can replace x with 50 and verify if it's good.10 = 180 - (50) - 3(90-(50)) --->
10 = 130 - 3(40) ---> 10 = 130 - 120 ---> 10 = 10 or 130 -130 = 0
It's good!

10=180-x-3(90-x)
10 = 180 - x - 270 + 3x
100 = 2x
x = 100/2 = 50
I got the same answer!
10 = 180 - x - 270 + 3x
100 = 2x
x = 100/2 = 50

10 = 180 - x -3(90 - x)
10 = 180 - x -270 + 3x
10 = 2x - 90
10 + 90 = 2x
2x = 100
x = 50
10 = 180 - x -270 + 3x
10 = 2x - 90
10 + 90 = 2x
2x = 100
x = 50

2(x + 5) = 18 + x 2x +10 = 18 + x -x -x x + 10 = 18 -10 -10 x = 8 x = 8 is the answer

10 = 180 - x - 3(90 - x)
10 - 180 = -x - 3*90 + 3*x
-170 = -x - 270 + 3x
3x - x = -170 + 270
2x = 100
x = 100/2
x = 50
10 - 180 = -x - 3*90 + 3*x
-170 = -x - 270 + 3x
3x - x = -170 + 270
2x = 100
x = 100/2
x = 50

10=180-x-270+3x, 100=2x, x=50
