Question

need help asap

Answer 1

\[2x-5y=11\]

Answer 2

4x+10y=18

Answer 3

i am doing elimination method

Answer 4

i got x=5 but ik thats wrong

Answer 5

2x - 5y = 11
solve for x
add 5y to both sides
2x = 11 +5y
divide both sides by 2 to isolate x
x = (11+5y)/2
Now insert that into equation in place of x to solve for y

Answer 6

2((11+5y)/2) -5y = 11
solve for y

Answer 7

once you know y without a variable you can plug back in to solve x

Answer 8

2x−5y=11 <--so for elimination lets multiply this equation by 2
4x+10y=18

4x-10y=22
4x+10y=18
8x=40
x=5 this is indeed correct

Answer 9

i have checked with a calculator and other methods

Answer 10

and y= -1/5

Answer 11

2x−5y=11
2(5)-5y=11
10-5y=11
-5y=1
y=-1/5 yes
