Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.
X - 2y = -24
x - y = 4
Isolate x in the first equation by adding 2y to both sides.
x = -24 + 2y
Now plug in this value of x into the second equation.
(-24 + 2y) - y = 4
Solve. Combine all like terms, 2y - y.
-24 + y = 4
Add 24 to both sides to isolate y.
y = 28
Now plug y back into the first equation to find x.
x - 2(28) = -24
x - 56 = -24
Add 56 to both sides to isolate x.
x = 32
The solution is (32, 28).
Answer:
it should be 2/12 and 9/11
Step-by-step explanation:
Answer:-3/4
Step-by-step explanation:
Get the x by itself by dividing both sides by 8 then reduce -6/8. When you reduce you get -3/4
Answer:
-3
Step-by-step explanation:
f(x) = x2 – 4
replace x with -1
f(-1) = (-1)^2 – 4
= -3
