Answer:
44%
Step-by-step explanation:
137650 x 0.44 = 60566
60566 + 137650 = 198216
Hope this helped!
2x -3y = 13
4x -y = -9
Multiply the second equation by -3 to make the coefficient of Y opposite the first equation.
4x -y = -9 x -3 = -12x + 3y = 27
Now add this to the first equation:
2x -12x = -10x
-3y +3y = 0
13 +27 = 40
Now you have :
-10x = 40
Divide each side by -10:
x = 40 / -10
x = -4
Now you have a value for x, replace that into the first equation and solve for y:
2(-4) - 3y = 13
-8 - 3y = 13
Add 8 to both sides:
-3y = 21
Divide both sides by -3:
y = 21/-3
y = -7
Now you have X = -4 and y = -7
(-4,-7)

Answer:
x= - 41/6, y= -6/23
Step-by-step explanation:
2x - 3y= - 1 ...(1)
0.8x - 3.5y=1/5 ...(2)
(2)×10 : 8x - 35y= 2 ... (3)
(1)×4 : 4x-12y= - 4 ...(4)
(3)-(4): 8x-35y=2
8x-12y= -4
_________
- 23y= 6
y= - 6/23
Substitute y= - 6/23 into any equation
Exp : 2x - 3(-6/23) = - 1
2x+18/23 = - 1
2x = - 41/3
x= - 41/6
True because to solve the problem you can do 4-7 and that is -3 and when there is a negative you must switch the inequality sign
