Heeelp . Can someone please answer this to meee ? .

Answer:

If f(x)=g(x), the solution is x=-2

Step-by-step explanation:

We are given:

$f(x)=3x+3\\g(x)= (-1/2)x-4$

We need to find the solution if f(x)=g(x)

Now solving for f(x)=g(x)

$f(x)=g(x)\\3x+3=(-\frac{1}{2}x)-4\\3x+3=-\frac{1}{2}x-4\\3x+\frac{1}{2}x=-4-3\\\frac{3x*2+x}{2}=-7\\\frac{6x+x}{2}=-7\\\frac{7x}{2}=-7\\x=-7*\frac{2}{7}\\x=-2$

If f(x)=g(x), the solution is x=-2
