I would subtract the 2nd from the first one
so -4x - -2x = -2x
4y - 4y = 0
-20 - -2 = -18
-2x = -18
now I would divide that by -2 to get the value for x
so no we have x = 9
now you just have to substitute that into one of the equations and simplify to get y
-2 X 9 + 4y = -2
-18 + 4y = -2
4y =16
y = 4
We want to solve the equation :

first, multiply both sides by 4:


divide both sides by 3:

add -3 to both sides:

Answer: x=9
Answer:1:00
Step-by-step explanation:mark me as brainliest
they have the same amount of sides as they do angles,
Type it into Google and it will solve for you.
100^(1/2)-125^(1/3) = 10-5 = 5
