x+4(2x+3)=15

x + 4 (2 x + 3) = 15

x = \frac{1}{3}

Decimal Notation

x = 0.33333 \dots

Solution steps

x + 4 (2 x + 3) = 15

Expand

4 (2 x + 3) : 8 x + 12

x + 8 x + 12 = 15

Add similar elements:

x + 8 x = 9 x

9 x + 12 = 15

Move

12

to the right side

9 x = 3

Divide both sides by

9

x = \frac{1}{3}

- 22 - x = 5 + 6 x + 9

x, 3 n (H x - 5 y) = 2 x

3 x + 1 = 8

x, - 3 y + 5 x = x y - 9

a, a + b + c = 4
