Answer:
(2,2)
Step-by-step explanation:
first take x-y=0 and multiply it by -5 you will then get this
-5x+5y=0
5x-2y=6
add those together
3y=6
divide by 3
y=2
now plug 2 in for y
x-2=0
add 2 to both sides
x=2
Use the equation 459/x=85/100. then you cross multiply 459 and 100 to get 45900. after that you divide 45900 by 85 to get x=540
149 will be rounded to 150 so 150×5= 750
16%. You divide those two numbers and then multiply the answer by 100
