Question

WILL FAN AND MEDAL!!!!
Solve the system of equations.

5x + y = 9
3x + 2y = 4

(-2, 5)
(1, 4)
(2, -1)
(4, -4)

Answer 1

Multiply the first equation by 2

Answer 2

ok

Answer 3

then subtract the 2nd from 1st equation

Answer 4

wait would you plug in 2 for one of the variables

Answer 5

you will get x, and substituting the value of x in any of those equation you will get y, hence the question is solved

Answer 6

10x+2y=18
3x+2y=4
subtracting we get
7x=14
x=2

Answer 7

putting x=2 in 2nd equation we get
3(2)+2y=4
y=-1

Answer 8

oh thank you but I just solved it by plugging the options given to me but thanks because that will help on non multiple choice test

Answer 9

ok
