Step-by-step explanation:

x+y=3.

2x+2y=6. ---------1

2x+5y=12. ---------2

subtract equation 1 from 2

3y=6

y=2

and x=4

Answer 2

We can see in the figure that two lines intersect at a point in 1st quadrant

Multiply 1st equation on both sides by 2

• 2x+2y=6
• 2x+5y=12

Subtract two equations ;

• 3y=6
• y=2
• x=3-y=3-2=1
• x=1,y=2
