Solve the following equation and write the test process 5 (x-3) = 55 4 (x + 8.2) = 40.8 (X-9) 7 = 6

Solve the following equation and write the test process 5 (x-3) = 55 4 (x + 8.2) = 40.8 (X-9) 7 = 6

Question 1: 5x-15 = 55, 5x = 40, x = 8
Question 2: 4x + 32.8 = 40.8, 4x = 8, x = 2
Question 3: move to the simple level of X-9 = 42 and x = 51. You'd better think about what the teacher said

How to solve the equation 49-x * x = 25 - (6-x) * (6-x)

49-x*x=25-36-x*x+12x
60=12x
x=5

9.3+ x=6.

9.3+x=6.2
Subtract another addend from plus = and
x=6.2-9.3
x=-3.1

I can't solve this equation well. 95-3x = 2x + 60
95-3x = 2x + 60 I can't solve this equation

Shift 95-3x = 2x + 60
　　　　　　95－60＝2x＋3x
　　　　　　35＝5x
　　　　　　x＝7
