Answer 2

answer

EQ.1 3x-y=-5

• 3x=-5+y
• x=(-5+y)/3

substituting the value of x in eq.2

2x+3y=-7

• 2{(-5+y)/3}+3y=-7
• (-2+2y)/3+3y=-7
• (-2+2y+9y)/3=-7
• -2+11y=-21
• 11y=-19
• y= -19/11

now putting the value of y in eq.1 to find x

3x-(-19/11)=-5

• 3x+19/11=-5
• 3x=-5-19/11
• 3x=(-55-19)/11
• 3x=-74/11
• x=-74/33
