Question

Solve the following system of linear equations graphically 5x - 7 Y = -50 and 5 x + 7Y = 20 also write the coordinators of the points where they meet x-axis shade the triangular region.
PLEASE GIVE THE ANSWER.
AND PLEASE DON'T POST THE SILLY ANSWER.

Answer 1

Given system of equations are
5x-7y=-50---1
5x+7y=20---2
Add equation 1 and 2 we get
10x=70
X=70/10
X=7
Put x=7 in equation 1 we get
35-7y=-50
-7y=-85
Y=12.14

Answer 2

step by step explaination:

we first take the linear equations as

5x-7y=-50 as eq(1)

5x+7y=20 as eq(2)

now we should add eq (1) and (2)

10x=70

x=70/10=7

now put in eq 1 then we get

35-7y=-50

-7y=-85

y=12.14

therefore y=12.14

hope it help u
