Question

solve by substition method. 3x+y-2=0 & 2x-3y-5=0​

Answer 1

Answer:

3x+y-2=0eq...1

2x-3y-5=0 eq... 2

Then rewrite eq... 1 as y=2-3x

Put y value in eq.... 2.

Then we get

2x-3(2-3x) - 5=0

2x-6+9x-5=0

11x-11=0

x=1

Put x=1 in eq.... 1

3(1) +y-2=0

y=-1

Order pair of equation is (x, y) =(1, - 1).
