Question

4•x+20=100 решить надо

Answer 1

4х + 20 = 100
4х = 100 - 20
4х = 80
х = 80 : 4
х = 20

Answer 2

4х=100-20 (умножение между 4 х не пишется)

4х=80

х=80:4

х=20

Ответ: х=20

Answer 3

To solve the equation 4x + 20 = 100, you need to isolate the variable x on one side of the equation. Follow these steps:

Step 1: Get rid of the constant term on the left side of the equation by subtracting 20 from both sides: 4x + 20 - 20 = 100 - 20 4x = 80

Step 2: Now, isolate x by dividing both sides of the equation by 4 (the coefficient of x): 4x/4 = 80/4 x = 20

The solution to the equation is x = 20.
