Question

0,8х + 0,01х + 0,214=0,7

Answer 1

0,8х + 0,01х + 0,214 =0,7
0,81x = 7 - 0,214
0,81x = 0,486
x = 0,486 ÷ 0,81
x = 0,6

Answer 2

0,81х+0,214х=0,7
0,81х=0,7-0,214
0,81х=0,486
х=0,486/0,81
х=0,6

Answer 3

To solve the equation 0.8x + 0.01x + 0.214 = 0.7, we can combine the terms with x and then isolate x.

First, let's combine the terms with x: 0.8x + 0.01x = 0.81x

Now, the equation becomes: 0.81x + 0.214 = 0.7

Next, we can subtract 0.214 from both sides of the equation to isolate the term with x: 0.81x = 0.7 - 0.214 0.81x = 0.486

Finally, to solve for x, we divide both sides of the equation by 0.81: x = 0.486 / 0.81 x ≈ 0.6

Therefore, the solution to the equation 0.8x + 0.01x + 0.214 = 0.7 is approximately x = 0.6.
