-3y = -4x +51

y = 4/3 - 17

there you go

y=3

4(15)-3y=51

60-3y=51

(subtract 60 on both sides)

-3y=-9

(divide both sides by -3)

and you get 3

What is the answer to -12=x+8divided by -3

AysviL [449]

$- 12 = x + \frac{8}{ - 3}$

$- 12 - ( \frac{8}{ - 3} ) = x$

$- 12 - \frac{8}{3} = x$

$\frac{ - 36}{3} - \frac{8}{3} = x$

$\frac{ - 36 - 8}{3} = x$

$\frac{44}{3} = x$

Is (6,-10) a solution of y=3x-8

Vitek1552 [10]

You can easily test this if you know that (6, -10) corresponds to (X, Y). Knowing this, you can:

X = 6
Y = -10

you put this into your equation:

-10 = 3*6 - 8

calculate it:

-10 = 18 - 8
-10 = 10
This is not true of course, -10 is not equal to 10. Therefore, (6, -10) is not a solution of y = 3x-8 :)
