Answer:
What YOUR PROBLEM
Step-by-step explanation:
-4.5x-2y=-12.5 and 3.25x-y=-0.75
we first multiply the second equation by -2
(-2)*(3.25x-y=-0.75)=-6.5x+2y=-1.5
add the equation to eliminate the y
so yo get (-4.5x-6.5x)=(-12.5-1.5)
-11x=-11
x=1
now we plug in x into any equation to solve for y
-45x-2y=-12.5 and x=1
(-45*1)-2y=-12.5
-4.5-2y=-12.5
-2y=-12.5+4.5
-2y=-8
y=4
then your answer is x=1 and y=4
Answer: 1100
Step-by-step explanation: mark x for the total sum.
0.35x+ 0.20x + 495 = x. 495= x-0.35x-0.20x
495= 0.45x. X= 495/0.45
