Answer:
x = 15
Step-by-step explanation:
create a proportion: <u> x + 10 </u> = <u> x + x + 10 </u>
5 8
cross-multiply: 8(x + 10) = 5(2x + 10)
8x + 80 = 10x + 50
80 = 2x + 50
30 = 2x
15 = x
Answer:
y=21-7x
-7 is your slope
21 is your y-intercept
Step-by-step explanation:
you send the 4x the other side and you send the other side opposite so it going to be -4x
-3y= 24-4x
than you divide -3 on 24 and -4x
