Question

If x=2a + 1and y = a -1 is a solution of the equation 2x-3y=5, find the value of “a”.

Answer 1

Step-by-step explanation:

2x - 3y = 5

2(2a+1) - 3(a-1) = 5

4a +2 -3a +3 = 5

a +5 = 5

a = 0

Answer 2

Answer:

a=o

Step-by-step explanation:

here,

2x-3y=5

we have x=2a+1 and y=a-1

2(2a+1)-3(a-1)=5

4a+2-3a+3=5

a+5=5

∴a=0
