Question

solve the following equations by elimination method
2x+y=12
3x-y=13​

Answer 1

Since the coefficients of y are the same, we do not need to modify the equations.

Thus,

2x + y = 12

+ 3x - y = 13

y +(-y) = y-y

=0

2x+3x=5x

12+13=25

5x=25

x=5

2(5)+y=12

10+y=12

y=2

Answer : x is 5 and y is 2

Answer 2

Answer:

2x +3x+y-y+12+13

5x ,25
