Calculators Rock!!!
Answer:
Step-by-step explanation:
The given functions are
and
By the algebraic properties of functions:
We just have to substitute to obtain:
The first choice is correct.
X = 3y - 6....so sub 3y - 6 in for x in the other equation
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y = 8 + 12
2y = 20
y = 20/2
y = 10
x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x = 24
solution is (24,10)
