Answer:
infinitely many solutions
Step-by-step explanation:
We want to find solution to the system:
-4y=-20x+40
y+10=5x
We make y the subject in the second equation to get;
y=5x-10
We substitute y=5x-10 into the top equation to get:
We expand to obtain;
This implies that:
Therefore the system has infinitely many solutions.
Answer:
46
Step-by-step explanation:
not sure
X/2 +3y = 6 . . . . . . . . starting point
x/2 = 6 -3y . . . . . . . . subtract terms that don't have x
x = 2(6 -3y) . . . . . . . . multiply by the inverse of the x-coefficient
x = 12 -6y . . . . . . . . . expand if you like
3y = 6 -x/2 . . . . . . . . subtract terms that don't have y
y = (6 -x/2)/3 . . . . . . . multiply by the inverse of the y-coefficient
y = 2 -x/6 . . . . . . . . . expand if you like
I'm so hungry lol xD, the answer is C
Answer:
v=8
Step-by-step explanation:
Let's solve your equation step-by-step.
16v−9v=56
Step 1: Simplify both sides of the equation.
16v−9v=56
16v+−9v=56
(16v+−9v)=56(Combine Like Terms)
7v=56
7v=56
Step 2: Divide both sides by 7.
7v
7
=
56
7
v=8
hope this helps!
