Answer: 5y + x

Step-by-step explanation: As you first step to this problem, change all your minus signs to plus negatives.

To simplify, we can only combine what are called our like terms and in this problem, we have one y-term and we have a pair of like terms in our x-terms.

So let's start by combining our y-terms.

13y + -7y simplifies to 5y.

Now we have one x-term so we have 5y + x.

(e+3)(e-5) expanded and simplified

Zarrin [17]

Step-by-step explanation:

$(e + 3)(e - 5) \\ e \times e + e \times ( - 5) + e \times e + e \times 3 \\ { e}^{2} + ( - 5e) + {e}^{2} + 3e \\ {2e}^{2} + ( - 2e)$

In this type of math equation, you have to multiply all members from the first part with the second part.

Expanded:

$e \times e+e \times (-5)+e \times e+e \times 3$

simplified:

${2e}^{2} + ( - 2e)$

Solve for x in the diagram

Aliun [14]

Answer:

x=12

Step-by-step explanation:

The two angles shown are complementary angles, so the add to 90 degrees

x+42 + 3x = 90

Combine like terms

4x+42 = 90

Subtract 42 from each side

4x+42-42 = 90-42

4x = 48

Divide by 4

4x/4 = 48/4

x = 12
