Question

Algebra 1 9th grade HELP PLEASE!!!!
2x + y = 11
3x + 4y = 24

Answer 1

By setting the equations equal to each other, we can eliminate a variable.

Multiplying the top by -4 gives us:
-8x -4y = -44
3x+4y = 24

now add the two:

-5x=-20
x=4

plug back in:

2(4)+y=11
8+3
=11
3(4)+4(3)
=12 + 12
=24!
Check.

Answer 2

Forgot to add: x=4, y=3.

Answer 3

Can you do it with substitution pwz :3??

Answer 4

equation 1: 2x + y = 11
equation 2: 3x + 4y = 24

equation 1: y = 11-2x
plug it into equation 2

3x+4(11-2x) = 24

3x +44 -8x = 24

-5x = -20

x = 4

plug back into equation 1, now you know what x is.

y = 11-2x

post what you get for y.
