Solve by elimination using subtraction.<br> 2x + y = -5<br> 2x - 5y = 13
spayn [35]

Answer:

(- 1, - 3 )

Step-by-step explanation:

Given the 2 equations

2x + y = - 5 → (1)

2x - 5y = 13 → (2)

Subtracting (1) from (2) term by term will eliminate the x-0 term

0 - 5y - y = 13 - (- 5) , that is

- 6y = 18 ( divide both sides by - 6 )

y = - 3

Substitute y = - 3 into either of the 2 equations and solve for x

Substituting into (1)

2x - 3 = - 5 ( add 3 to both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

solution is (- 1, - 3 )

Find the value of x needed to make the equation true.<br> 8x – 4 = 13x + 6
Kipish [7]

Answer:

x = -2

Step-by-step explanation:

<u><em>First, you need to subtract 8x from both sides:</em></u>

8x – 4 = 13x + 6

-8x         -8x

____________

-4 = 5x + 6

<em><u>Then, subtract 6 from both sides:</u></em>

-4 = 5x + 6

-6         - 6

________

-10 = 5x

<u><em>Lastly, divide both sides by 5:</em></u>

-10 = 5x

-2 = x
