Question

Х+40=110. Х-30=170. 300-х=250.

Answer 1

X + 40 = 110

X = 110-40 = 70;

X - 30 = 170

X = 170 + 30 = 200;

300 - X = 250

X = 300 - 250 = 50.

Answer 2

Х+40=110
Х=110-40
Х=70

Х-30=170
Х=170+30
Х=200

300-Х=250
Х=300-250
Х=50

Answer 3

To solve these equations for the value of Х, follow these steps:

1. Х + 40 = 110 To find Х, subtract 40 from both sides of the equation: Х = 110 - 40 Х = 70

2. Х - 30 = 170 To find Х, add 30 to both sides of the equation: Х = 170 + 30 Х = 200

3. 300 - Х = 250 To find Х, subtract 250 from both sides of the equation: Х = 300 - 250 Х = 50

So, the solutions for Х are: Х = 70, 200, and 50.
