Answer:

The value of x is 4 and y is (-9)

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • x + 2y = -14
  • x – y = 13
<h3><u>To </u><u>Find</u>;</h3>
  • Value of x
  • Value of y
  • By Elimination Method

Now, Name the equation

x + 2y = -14 ...(1)

x – y = 13 ...(2)

Now,

x + 2y = -14

x – y = 13

<u>– + –</u>

3y = -27

y = -9

Now, put the value of y in equation 2

x – y = 13

x – (-9) = 13

x + 9 = 13

x = 4

Thus, The value of x is 4 and y is (-9)

<h3><u>For </u><u>Verification</u>;</h3>

x + 2y = -14

4 + 2(-9) = -14

4 – 18 = -14

-14 = -14

x – y = 13

4 – (-9) = 13

4 + 9 = 13

13 = 13

Hence, L.H.S = R.H.S

Answer:

y=-25, x=-12

Step-by-step explanation:

1 subtract both equations from each other vertically.

x-x=0,

2y-y=1y

-14-13=-25

1y=-25

y=-25

2. Find x using y

x--25=13

x+25=13

x=-12

Solve for x using the given diagram
blagie [28]

Answer:

<h2>x = 1</h2>

Step-by-step explanation:

Look a t the picture.

The triangles on the picture are similar.

Therefore the sides are in proportion:

\dfrac{8x}{10}=\dfrac{4}{5x}              <em>cross multiply</em>

(8x)(5x)=(4)(10)

40x^2=40           <em>divide both sides by 40</em>

x^2=1\to x=\sqrt1\\\\x=1
