Question

2x+8(числитель)13(знаменатель)+15-x(числитель)26(знаменатель)=2

Answer 1

.....
2*(2х+8)+15-х+52
4х+16+15-х=52
4х-х=52-16-15
3х=21
х=7

Answer 2

$2x+ \frac{8}{13}+15- \frac{x}{26}=2 \\ 2x+15+ \frac{8}{13}- \frac{x}{26}=2 \\ 2x+15 +\frac{16-x}{26}=2 \\ 2x*26+15*26+16-x=2*26 \\ 52x+390+15-x=52 \\ 52x-x=52-390-15 \\ 51x=-353 \\ x=-6.92$

Answer 3

To solve this equation, we need to first simplify the left-hand side by combining like terms:

2x + (8/13) - (x/26) = 2 - 15

Multiplying both sides by the common denominator of 26*13=338, we get:

676x + 208 - 13x = -26*13

Simplifying further, we have:

663x = -338

Dividing both sides by 663, we get:

x = -338/663

Therefore, the solution to the equation is:

x = -338/663.
