What is the property of equality of 2y − 40 = -18?

Given the equation 2y-40=-18 to simplify the equation further we need to first add 40 to both sides of the equation thereby justifying the addition property as shown;

2y-40 + 40 =-18+40

2y = 40-18

2y = 22

We will also apply the division property here. Division property is used when both sides of an equation is divided by a number without affecting the equality rule.

Dividing the resulting equation by 2:

2y/2 = 22/2

y = 11

what level of math? also i don't need to be paid if i can you.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
