Y=2x

Y=7x-20

I’ll give you brainlessly

(4,8)

Step-by-step explanation:

y = 2x

y = 7x-20

Step 1: plug in 2x for y

Step 2: subtract 7x on both sides

Step 3: divide by -5 on both sides

Step 4: plug in 4 into y = 2x

2x = 7x -20

-7x      -7x

-5x  = -20

-5         -5

x = 4

y = 2(4)

y = 8

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

good job you smart son of a gun you are smarter that einstein. 7
