4x-3y=17......(1)
5x+4y=60......(2)
Multiply equation (1) by 4 and equation (2) by 3:-
16x - 12y = 68
15x + 12y = 180
Adding these 2 equations:_
31x = 248
x = 248/31 = 8
Now substitute x = 8 in equation (1):-
4(8) - 3y = 17
32-3y = 17
-3y = -15
y = -15/-3 = 5
So solution is x=8,y=5
The number -4 is a whole number
Answer:
All I see is white need to post another
Add 6 to both sides
2m2+7m+6=0
180- 113 = 67
180- 67= 113
<5= 67
<2=113
