Question

1,2x + 4,2x + 1,25 = 15​

Answer 1

5,4х+1,25=15
5,4х=15-1,25
5,4х=13,75
Х=275/108

Answer 2

1)5,4х+1,25=15

2)5,4х=15-1,25

3)5,4х=13,75

4)Х=275/108

Answer 3

To solve the equation, let's combine the like terms on the left side of the equation:

1.2x + 4.2x + 1.25 = 15

Combining the x terms gives us:

5.4x + 1.25 = 15

Next, let's isolate the variable x. We'll subtract 1.25 from both sides:

5.4x = 15 - 1.25

5.4x = 13.75

To solve for x, divide both sides of the equation by 5.4:

x = 13.75 / 5.4

Using a calculator, we can find:

x ≈ 2.5463

Therefore, the solution to the equation is x ≈ 2.5463.
