Question

X+1 2,8 ------ = ----- 3 4,2

Answer 1

Ответ:

Пошаговое объяснение:

4,2*(x+1) = 3*2,8

4,2x + 4,2 = 8,4

4,2x = 8,4 - 4,2

4,2x = 4,2

x = 4,2 : 4,2

x = 1

Answer 2

It looks like you've written an equation with fractions. The equation is:

(x + 1) / 2.8 = 3 / 4.2

To solve for x, you can cross-multiply and then solve for x:

Cross-multiply: 4.2 * (x + 1) = 2.8 * 3

Distribute: 4.2x + 4.2 = 8.4

Subtract 4.2 from both sides: 4.2x = 4.2

Divide by 4.2: x = 1

So, the solution to the equation is x = 1.
