Question

if x=2 y=2+x , 2x+3y+ 99= 10 find x&y

Answer 1

Hii friend,

X = 2

Y = 2 + X = 2 + 2 [ X = 2]

Y = 4

2X + 3 Y + 99 = 10.........(1)

Putting the Value of X and Y in equation (1)

2X +3Y + 99 = 10

2 × 2 + 3 × 4 + 99 = 10

4 + 12 + 99 = 10

115 = 10

115-10 = 114

Therefore,

2X + 3Y + 89 = 114.

And,

X = 2 , Y = 4

HOPE IT WILL HELP YOU......... :-)

Answer 2

Answer:

Step-by-step explanation:

Given x = 2,y = 2 + x

2x + 3y + 99 = 10

X = 2, y=2+2 = 4

Then,

2*2 + 3*(2+2) + 99 = 10

4 + 12 +99 = 10

10-115=-114

So,

x= 2

y= 4
