How do i round a solution to the nearest tenth?
y=-0.25x + 4.7
y= 4.9x - 1.64

The measure is X=4

Step-by-step explanation:

you set the expressions equal to each other and find the value of X

so you have 20x+60 and 30x+20

you set them equal to each other and it looks like 20x+60=30x+20

you move the 30x to the other side by subtracting it on both sides getting

-10x + 60= 20

next you move the 60 to the other side getting -10x=-40

then you divide -10 on both sides getting x=4
