Question

if x=2-a and y=2+a is a solution of the equation 3x-2y+6=0 find the value of a . find three nore solutions if the resultant equation​

Answer 1

Step-by-step explanation:

3x-2y+6=0

put the value of x=2-a and y=2+a

3(2-a)-2(2+a)+6=0

6-3a-4-2a+6=0

-3a-2a+6-4+6=0

-5a+8=0

-5a=-8

a=-8/-5

a=8/5

Answer 2

3x-2y +6 = 0

3(2-a) -2(2+a) +6 =0

6-3a -4 -2a +6 =0

-5a+8 = 0

-5a = -8

a= 8/5
