<h3>
Answer: x + y = 2</h3>
====================================================
Work Shown:
y - 6 = -(x + 4)
y - 6 = -x - 4
y = -x - 4 + 6 ..... adding 6 to both sides
y = -x + 2
y + x = 2 .... adding x to both sides
x + y = 2
The equation is in standard form Ax+By = C, with A = 1, B = 1, and C = 2.
You just need to substitute the values into the expression.
I always say hug it when you plug it...which means put ( )s around the number you are substituting into the expression.
-2ab² - 2b³
-2(-2)(-3)² - 2(-3)³
-2(-2)(9) - 2(-27)
4(9) - 2(-27)
36 + 54
90
The answer is a. 90
