Question

Solve the system of equations using any method
X=4y
3x-2y=20

Answer 1

well we know x = 4y
so,

3(4y) - 2y = 20

solve for y
then sub the value of y into the first equation to solve for x

Answer 2

12-2y=20

Answer 3

where did the y go?

Answer 4

12y-2y=20

Answer 5

do you not know how to solve from that point for y?

Answer 6

Just factor out the y

Answer 7

10y=20
y=2?? is this corect

Answer 8

yup

Answer 9

now sub it into one of the original equations and solve for x and you have your solution

Answer 10

y=2 x= 8

Answer 11

the point where the two lines intersect :)

Answer 12

is this corect??

Answer 13

yes it is correct
