2/3 = x/(3x + y)

Cross multiply:

3x = 2(3x + y)

Distribute 2:

3x = 6x + 2y

Subtract 6x to both sides:

-3x = 2y

Divide 'y' to both sides:

-3x/y = 2

Divide -3 to both sides:

x/y = -2/3

2/3 = x/3x + y
2(3x + y) = 3x
2(3x) + 2(y) = 3x
 6x + 2y = 3x
 - 6x - 6x
 2y = -3x
 2 2
 y = -1.5x

If f(x) = x2 – 2x and g(x) = 6x + 4, for which value of x does (f + g)(x) = 0?

alekssr [168]

G(f(x)) = 2(x^2 -1) + 3

= 2x^2 + 1

subsitute 2

= 9

Hence, the answer is 9
