Question

solve the pair of linear equation by the substitution method x+y=5 and 2X-3y=5
​

Answer 1

Step-by-step explanation:

x=5-y

substitute the value of x in equation 2

2(5-y) -3y=5

10-2y-3y=5

-5y=-5

y=1

so,by putting the value if y in equation 1

x+ 1=5

x=4

hence the value of x is 4 and the value of y is 1
