Question

Solve this system for equations using substitution. Put your answer in ordered pair form(x,y)

x=4y
3x-2y=20

Answer 1

Place 4y in place of x in the second equation....
like \[3(4y)-2y=20\] Now you try.

Answer 2

x=4y
3x-2y=20
3(4y)-2y=20
12y-2y=20
10y = 20
y= 2
put y = 2 in
x= 4y
x = 4*2
x = 8
(8,2)
