Question

What is the solution for the System of
Equations below?

y=-2x+7

y =2x- 13

Answer 1

Answer:

❥ Given ,

❥ y = - 2x + 7 ---------- ( 1 )

❥ y = 2x - 13 ----------- ( 2 )

☑️Equating ( 1 ) and ( 2 ) , we get :

$- 2x + 7 = 2x - 13 \\ \\ = > - 2x - 2x = - 13 - 7 \\ \\ = > - 4x = - 20 \\ \\ = > 4x = 20( - \: and \: - \: cancelled) \\ \\ = > x = \frac{20}{4} \\ \\ = > x = 5$

❥ Now putting back the value of x in equation 1 :

$y = - 2x + 7 \\ \\ = > y = - 2 \times 5 + 7 \\ \\ = > y = - 10 + 7 \\ \\ = > y = - 3$

✧ When we put the value of x in 2nd equation we will get ( - 3 ) itself .

✧ So x = 5 and y = ( - 3 )

Answer 2

Answer:

2x+7=2x−13

=>−2x−2x=−13−7

=>−4x=−20

=>4x=20

=>x=

4

20

=>x=5

y = - 2x + 7 \\ \\ = > y = - 2 \times 5 + 7 \\ \\ = > y = - 10 + 7 \\ \\ = > y = - 3

y=−2x+7

=>y=−2×5+7

=>y=−10+7

=>y=−3
