Question

3(x + y + 1)-2(x-5- y)= 24
(5(-2x - 3y + 4)+4(1+ 3x +2y)=12'​

Answer 1

3*(x+y+1)-2*(x-5-y)=24                                

3x+3Y+3-2x+10+2y=24

x+5y=24-3

x+5y=21

x=21-5y

5*(-2x-3y+4)+4*(1+3x+2y)=12

-10x-15y+20+4+12x+8y=12

2x-7y+24=12

2x-7y=12-24

2x-7y= -12

2*(21-5y)-7y= -12

42-10y-7y= -12

42-17y= -12

42+12= 17y

17y= 54

y=54:17

y=3,1

x=21-5y=21-5*3,1=21-15,5

x=5,5
