-2x=15-7y
x=-7.5+3.5y
-3x-8y=4
-3(7.5+3.5y)-8y=4
-22.5-10.5y-8y=4
-22.5-18.5y=4
-18.5y=4+22.5
-18.5y=26.5
y=-53/35
the fraction might not be in lowest terms.
Answer:
D
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² - 4 - (x + 2) ← distribute parenthesis by - 1
= 3x² - 4 - x - 2 ← collect like terms
= 3x² - x - 6
Gosh that looks hard. but i wish you the best of luck on it
