Question

If x=5 is a solution of 3x+2y+25=0,2x+y+10=0 then the value of y is​

Answer 1

ANSWER

Y=-20

Step-by-step explanation:

x=5

3(5)+2y+25=0

15+2y+25=0

40=2y

y=40/2

y=-20

x=5

2(5)+y+10=0

10+y+10=0

20y=0

y=-20

Answer 2

Answer:

y=-20,-20

Step-by-step explanation:

given X=5

the equation is 3x+2y +25=0

substitute X=5 in above equation

3(5)+2y+25=0

15+2y+25=0

2y+40=0

2y=-40

y=-40/2

y=-20

the given equation is 2x+y+10=0

substitute X=5 in above equation

2(5)+y+10=0

10+y+10=0

20+y=0

y=-20
