4x - 5y = -12
-x + 5y = 18
Add the equations together:
4x + -x = 3x
-5y + 5y = 0
-12 + 18 = 6
So now you have:
3x = 6
Divide both sides by 3:
X = 2
Now you have the value of x, replace x with 2 in one of the equations and solve for y:
4(2) -5y = -12
8 -5y = -12
Subtract 8 from both sides:
-5y = -20
Divide both sides by -5:
Y = 4
The solution is x = 2 and y = 4 which is written as (2,4)
The correct answer is 1.25 dollars per pound. You can check it by multiplying it with 4.16
Since you didn’t put the numbers to find the amount, I’ll teach you how to.. Once you have the decimal figure, multiply it by the number for which you seek to calculate the percentage
The correct answer is 6,8
