Question

3.97x+20.04x+0.63x=5050 80.6-(х-7,98)=63,4

Answer 1

$3.97x+20.04x+0.63x=5050\\24,64x=5050\\x=\frac{61325}{308}\\\bold{x=204\frac{293}{308}}$

$80,6-(x-7,98)=63,4\\80,6-x+7,98=63,4\\88,58-x=63,4\\-x=63,4-88,58\\-x=-25,18\\\bold{x=25,18}$

Answer 2

Let's solve the two equations step by step.

1. 3.97x + 20.04x + 0.63x = 5050

Combine the x terms on the left side:

4.60x = 5050

Now, isolate x by dividing both sides by 4.60:

x = 5050 / 4.60 x ≈ 1097.83

So the solution for the first equation is x ≈ 1097.83.

2. 80.6 - (x - 7.98) = 63.4

First, simplify the expression in parentheses:

80.6 - x + 7.98 = 63.4

Now, combine like terms:

88.58 - x = 63.4

Next, isolate x by subtracting 88.58 from both sides:

-x = 63.4 - 88.58

Simplify:

-x = -25.18

Finally, to get x by itself, multiply both sides by -1 (since we have -x):

x = 25.18

So the solution for the second equation is x = 25.18.

Therefore, the two solutions are:

1. x ≈ 1097.83
2. x = 25.18
