Question

if x=2-a and y=2+a is a solution of the equations 3x-2y+6=o find the value of 'a' find three mare solutions of the resultant equation​

Answer 1

Answer:

3x +2y-6=0

x=2-a, y=2+a

substitute the values given.

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

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

4-a=0

a=4

that's the value of a

mare solution

x=0 -2 -4

y=3 0 3

that's the answer.
