We are given that y varies directly with c.

We need a constant of proportionality. I decided to let c be the constant of proportionality.

y = cx

7 = 2c

7/2 = c

We are now given the value of y to be 84 and must find x.

y = cx

84 = (7/2)x

84 ÷ (7/2) = x

24 = x

Answer:

x=24

Step-by-step explanation:

y = x*c

x=2, y=7

2*c=7 => c=7/2

x*7/2 = 84

x = 84*2/7

x = 12*2

x = 24

AlekseyPX

Answer:

x = -1

Step-by-step explanation:

use distribution

3x + 3 = -2x + 2 - 4

simplify

3x + 3 = -2x - 2

combine like terms

3x + 3 = -2x - 2

-3x                -3x

3 = -5x - 2

+2         +2
