2(x-7)2-31=1

2 (x - 7) 2 - 31 = 1

x = 15

Solution steps

2 (x - 7) \cdot 2 - 31 = 1

Multiply the numbers:

2 \cdot 2 = 4

4 (x - 7) - 31 = 1

Move

31

to the right side

4 (x - 7) = 32

Divide both sides by

4

x - 7 = 8

Move

7

to the right side

x = 15

5 y = 24

y, 5 x - 4 y = 1

y, 5 x - 4 y = 8

- 3 x - 12 = 20

f, f (x - 1) = \frac{x + 1}{x ^{2} - 5 x + 6}
