Question

Ifx=a, y=b is the solution of the equations x+y=5 and 2x-3y=4, the value of a and b are respectively​

Answer 1

Answer:

a=19/5 and b=6/5

Step-by-step explanation:

a+b=5

or, a=5-b

2a-3b=4

or, 2×(5-b)-3b=4

or, 10-2b-3b=4

or, 10-5b=4

or, b=6/5

So,

a=5-6/5

a=19/5

so,a=19/5 and b=6/5
