y=10x+20
y=10×5y+20
y=50y+20
-20=50y-y
-20=49y
y=-20/49

Answer:

x = -2.04

y = - 0.408

Step-by-step explanation:

this is a solve by substitution problem. you know what x is from the first equation so you plug that into the second equation and solve for y. then when you know y you can plug y back into any equation to find x.

y=10(5y)+20 (substitute x)

y=50y+20 (subtract 50y from both sides)

-49y=20 (divide each side by -49)

y= -0.408

x=5(-0.408) (plug y in)

x= -2.04
