Question

Solve the system of equations.

5y−4x=−7

2y+4x=14

y=

x=

Answer 1

Answer:

10y-8x=-14

10y+20x=70

Step-by-step explanation:

-10x=56 x= 0.17

Answer 2

Answer:

according to question :-

5y-4x=-7

2y+4x=14

so adding the first equation add second equation then it will be (5y-4x)+(2y+4x)=7+14

5y-4x+2y+4x=21

7y=21

then y 21/7=3

so y=3

now putting the value of y in equation 1

so

5y-4x=-7

5*3-4x=-7

15-4x = -7

-4x = -7-15

-4x=-22

x=-22/-4 = 5.5

x=5.5

y=3
