Given the equations y-3x=8 and 3x=2y+7 what would you substitute for Y in the equation 3x=2y+7 A.8-3x

B.8/3×

C.8+3x

D.8(3x)

hel pleas fas

8+3x

Step-by-step explanation:

Look at the first equation. If you add 3x to both sides of the equation, it becomes y-3x+3x=8+3x. Y-3x+3x is the same thing as just y, so the equation is really saying y=8+3x. Replace y in the other equation with 8+3x.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

i would need to see the dot plot : )
