Answer 1

X+57=70
x=70-57
x=13

26-x=16
x=26-16
x=10

y-50=80
y=80+50
y=130

Answer 2

1) x+57=70
х=70-57
х=13
-----------
Ответ: х=13.

2) 26-x=16
-х=16-26
-х=-10
х=10
------------
Ответ: х=10.

3) у-50=80
у=80+50
у=130

Ответ: у=130.

Answer 3

To solve these equations, follow these steps:

1. Solve for x in the first equation: X + 57 = 70 Subtract 57 from both sides to isolate x: X = 70 - 57 X = 13

2. Solve for x in the second equation: 26 - x = 16 Subtract 16 from both sides to isolate x: -x = 16 - 26 -x = -10 Divide both sides by -1 to solve for x: x = 10

3. Solve for y in the third equation: y - 50 = 80 Add 50 to both sides to isolate y: y = 80 + 50 y = 130

The solutions to the equations are: X = 13 x = 10 y = 130
