How do i do this 2y=-x+8 4x-2y+18

x=4/31y + -18/31

Step-by-step explanation:

Let's solve for x.

2y=−x+(8)(4)x−2y+18

Step 1: Flip the equation.

31x−2y+18=2y

Step 2: Add 2y to both sides.

31x−2y+18+2y=2y+2y

31x+18=4y

Step 3: Add -18 to both sides.

31x+18+−18=4y+−18

31x=4y−18

Step 4: Divide both sides by 31.

31x/31 = 4y-18/31

x=4/31y + -18/31

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

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
