Question

0,7х+0,2х=3,528 ????????????

Answer 1

0,7х+0,2х=3,528
0,9x=3,528
x = 3,528/0,9
x = 3,92

Answer 2

To solve the equation 0.7x + 0.2x = 3.528, you can combine the like terms on the left side of the equation and then solve for x:

0.7x + 0.2x = 3.528

Combine the x terms:

(0.7 + 0.2)x = 3.528

Now, add the coefficients:

0.9x = 3.528

Next, isolate x by dividing both sides by 0.9:

x = 3.528 / 0.9

Now, calculate the value of x:

x ≈ 3.92

So, the solution to the equation is approximately x ≈ 3.92.
