Question

Solve the system of equations by using substitution or elimination and choose the correct ordered pair.

Answer 1

Answer:

we get y = 3 x = 4

Step-by-step explanation:

so we have to cancel one out we'll use u

mutiply top by -2 to everything

add all the numbers and we get -5x=-20 multiple by -1

then divide both sides by 5

x=4 then use that and input it in any of the two beginning equations

x(4) +2y = 10

4 + 2y = 10 -4

-4

2y=6

y=3
