9 Find the sum of (x + 5), (-4x – 2), and (2x – 1).

here

Step-by-step explanation:

(x+5) is x+5

(-4x-2) is -4x-2

(2x-1) is 2x-1

-x + 2

Step-by-step explanation:

So I assume that the question would be set up like this if you are finding the sum of all 3 terms:

(x + 5) + (-4x - 2) + (2x - 1)

1) Take out parentheses

x + 5 - 4x - 2 + 2x - 1

2) Add like terms

For the x terms:

x - 4x = -3x

-3x + 2x = -x

For the other terms:

5 - 2 = 3

3 - 1 = 2

The sum of the terms is -x + 2

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
