Which of the following statements correctly illustrate the addition property of equality? Check all of the boxes that apply.

If a = b, then a + c = b + c.

If x = y, then x + 2 = y- 2.

If w + 2 = 7, then w + 2-2 = 7- 2.

If z-2/5=9, then z-2/5 + 2/5=9-2/5.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
