2x(3x+5)=6x(x)-2x-12

2 x (3 x + 5) = 6 x (x) - 2 x - 12

x = - 1

Solution steps

2 x (3 x + 5) = 6 x (x) - 2 x - 12

Simplify

6 x (x) - 2 x - 12 : 6 x^{2} - 2 x - 12

2 x (3 x + 5) = 6 x^{2} - 2 x - 12

Expand

2 x (3 x + 5) : 6 x^{2} + 10 x

6 x^{2} + 10 x = 6 x^{2} - 2 x - 12

Subtract

6 x^{2} - 2 x

from both sides

6 x^{2} + 10 x - (6 x^{2} - 2 x) = 6 x^{2} - 2 x - 12 - (6 x^{2} - 2 x)

Simplify

12 x = - 12

Divide both sides by

12

x = - 1

- (v + 4) + 5 = 4 v + 1 - 5 v

- (- 3 h + 6) = 3 (- 10 + 3 h)

y, 2 x + 3 y = 7

a x - a (a + b) = - x - (1 + ab)

y, 2 x + 4 y = 8
