-7= -70+ y
jeez the answers are hard to find

63=y

Step-by-step explanation:

Add 70 to both sides to cancel it out. -7+-70=63. That leaves you with 63=y

63

Step-by-step explanation:

simplify both sides of the equation

-7 = y - 70

flip the equation

y - 70 = -7

add 70 to both sides

y - 70 + 70 = -7 + 70

y = 63

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
