How many solutions does the system of equations have 4x+16y=12 y=-1/4x+9/12

The first equation is ,

First we need to solve this equation for y , and for that we need to subtract 4x from both sides, that is

Now we need to get rid of 16, and for that we have to divide both sides by 16, that is

And the second equation is

And on simplifying we will get

Which is same as the firrst equation. And in that case, there are infinite or many solutions .

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
