2x-5(x-9)=15

2 x - 5 (x - 9) = 15

x = 10

Solution steps

2 x - 5 (x - 9) = 15

Expand

- 5 (x - 9) : - 5 x + 45

2 x - 5 x + 45 = 15

Add similar elements:

2 x - 5 x = - 3 x

- 3 x + 45 = 15

Move

45

to the right side

- 3 x = - 30

Divide both sides by

- 3

x = 10

7 x + 8 = 4 x - 10

L, A = L W

f = \frac{3}{2} \cdot (\frac{4}{3})^{1} - 1

a, a + b - c = 4

x, 2 y - x - 5 = 0
