Eliminate y by subtracting both equations
6x = 18
x = 3
y = 4

4x+3y=24
-2x+3y=6
since there is 3y in both the equation therefore it will be cancelled.
therefore we are left with 6x=18
x=3
substituting the value of x in the first equation,we get
4*3+3y=24
12+3y=24
or 3y=12
or y=4
therefore x=3 and y=4

4x+3y=24 -->1
3y-2x=6 multiply this equation by 2
=>6y-4x=12 --->2 Add equation 1 and 2
3y+4x=24
+6y-4x=12
____________
9y+0x=36
___________
9y=36 means y=4, substitute this y value in equation 1
=>4x+3*4=24
=>4x=24-12
=>x=12/4
=>x=3
therefore x=3 and y=4

4x + 3y = 24 ---------eq1
3y – 2x = 6 ----------eq2
subtracting eq2 from eq1
6 x = 18
x = 3
putting the value of x = 3 in eq 1
12 + 3 y = 24
or 3 y = 12
y = 4
Therefore x = 3 and y = 4

3y = 6 + 2x
3y = 24 - 4x
6 + 2x = 24 - 4x
3 + x = 12 - 2x
3x = 9
x=3
4x + 3y = 24
4(3) + 3y = 24
12 + 3y = 24
3y = 12
y = 4
3y - 2x = 6
3y - 2(3) = 6
3y - 6 = 6
3y = 12
y =4
(3, 4) is the solution

4x+3y=24----------(1)
3y-2x=6--------------(2)
=>-2x+3y=6-----(2)
substracting eq (1) from eq (2)
-2x+ 3y= 6 {+3y-3y=0}
4x+ 3y= 24
(-) (-) (-)
___________
-6x =-18
therefore 6x=18
x=18/6.
x=3.
putting the values of x=3 in eq (1)
4(3)+3y=24
12+3y=24
3y=24-12
3y=12
therefore y=12/3
y=4
therefore values of x=3;y=4;

4x+3y=24...........................(1)
-2x+3y=6...........................(2)
eqs (2) multyply by 2 then eqs will be -4x+6y=12.........(3)
subtract eqtion (3)frm (1)
then 9y= 36
y = 36/9
y =4
put y=4 in eqtion (1)
4x+3y=24
4x+3*4=24
4X=24-12
4X=12
X=12/4
X=3
HENCE X= 3 ,Y= 4 ANSWERS
u can prove that answer is true or false
4x+3y=24
put x=3 ,y=4 i eqtion
4*3+3*4=24
12+12=24
24=24
l.h.s is equal to r.h.s thus answer is right

Make y subject of equation1 y=24-4x/3
substitute into 2 3(24-4x/3)-2x=6
cross out both 3s as 3/3 = 1
so 24-4x-2x=6
-6x=-18
x=3
put x into equation 2
3y-2*3=6
3y-6=6
3y=12
y=4
so x-3, y=4
