Multiplying ,you get 18x^2+21x-24x-28. You simplify to get:
18x^2-3x-28.
Answer:
if im right its number 4!! if its not right sorry i did the math and thats what i got!!
Answer:
n-58
Step-by-step explanation:
Use substitution
-x + 4 = 1/3x + 8
4 = 4/3x + 8
-4 = 4/3x
x = -4 * 3/4
x = -3
Then plug x into one of the original equations. In this case y = -x + 4 is the easiest.
y = -(-3) + 4
y = 7
