Question

(x+30)* 1,2= x * 2,1​

Answer 1

Ответ:

x = 40

Пошаговое объяснение:

(x+30)1.2 = 2.1x

1.2x+36 = 2.1x

1.2x-2.1x = -36

-0.9x = -36

x = 40

Answer 2

(x+30)*1,2=x*2,1​

(х+30)*(6/5)=х*(21/10)

х+306/5=х*(21/10)

6х/5=21х/10-36

(-9)х/10=-36

х=-36/(-9/10)

х=40

Answer 3

It looks like you're trying to set up an equation involving multiplication. The equation you've written is:

(x + 30) * 1.2 = x * 2.1

To solve for the value of x, we can follow these steps:

1. Distribute the multiplication on the left side: 1.2x + 36 = 2.1x

2. Subtract 1.2x from both sides to isolate the x terms: 36 = 2.1x - 1.2x 36 = 0.9x

3. Divide both sides by 0.9 to solve for x: x = 36 / 0.9 x = 40

So, the solution to the equation is x = 40.
