Question

3x+y=15,2x-y=5 slove by elemination method ​

Answer 1

Answer:

Given equations-

3x+y=15 -eq.1

2x-y=5 -eq.2

Adding eq.1 and eq.2, we get-

3x+y+2x-y=15+5

》5x=20

》 x=20/5

》 x=4

Substituting this value of x in eq.1-

3x+y=15

》3(4)+y=15

》12+y=15

》y=15-12

》y=3

Hence, the value of x and y is 4 and 3 respectively.
