Solve using substitution.<br><br> x = –2<br> 5x + 3y = 14

Nookie1986 [14]

Answer: (-2, 8)

Explanation:

Plug x = -2 into the second equation. Isolate y.

5x+3y = 14

5(-2)+3y = 14

-10+3y = 14

3y = 14+10

3y = 24

y = 24/3

y = 8

We have x = -2 lead to y = 8.

Therefore, the ordered pair (x,y) = (-2,8) is the solution to this system.

If x is directly proportional to y and x= 4.5 when y = 3 find y when x = 24.

djverab [1.8K]

x=4.5 - - -> y=3

x=24 - - - -> y= n

4.5n= 72

n= 72/4.5

n= 16

the answer is C) 16
