✔ 最佳答案
4/1 - x/4 = 54 - x/4 = 5
-x/4 = 1
-x = 4
x = -4
CHECK:
4/1 - (-4)/4 = 5
4 + 1 = 5
5 = 5

1. Subtract (4/1)
2. Equals 1
3. Use cross multiplication
4. X = 4
2. Equals 1
3. Use cross multiplication
4. X = 4

Very easy! To begin with, let's get rid of the numbers on both sides:
4/1 just equals 4
So 4- x/4 = 5
-x/4 =5-4=1
-x/4=1
-x=4
x= -4
Done!
4/1 just equals 4
So 4- x/4 = 5
-x/4 =5-4=1
-x/4=1
-x=4
x= -4
Done!

Sunni, if I understand 4-x/4=5 segregate the constants
-x/4=1 divide by the coefficient of x (multiply by -4)
x=-4
-x/4=1 divide by the coefficient of x (multiply by -4)
x=-4

4/1 - x/4 = 5
x/4 = 4 - 5
x = 4(-1)
x = -4
x/4 = 4 - 5
x = 4(-1)
x = -4

4-5=x/4
-1=x/4
x=-4
-1=x/4
x=-4
