F(x) = -52x + 4
g(x) = -12x - 4
To find the solution of the system of equation, we have to just equate the equation to each other.
f(x) = g(x)
-52x + 4 = -12x - 4
-52x + 12x = - 4 - 4
-40x = -8
x =

x = 0.2
Answer:
7
Step-by-step explanation:
1) "x is 23 more than 3 times y" is the same thing as "x = 23 + 3y"
REMEMBER: when you see "is" replace is with an equals sign.
2) Solve for x with your new equation.
3) Plug 6 into the y ("y = 6")
x = 23 + 3 x 6... x = 23 + 18... x = 41
4) Plug in your variables, and evaluate.
(41 - 6)/5... 35/5... 7!
