What’s the solution to x-4y=-8 and 2x-3y=-16

Step-by-step explanation:

You can apply the elimination method:

- Multiply the first equation by -2.

- Add both equations to cancel out the variable x.

- Solve for y:

- Substitute y=0 into any of the original equations ans solve for x. Then:

The answers are:

Since we have to equations, first we need to isolate one variable, and then substitute it into the other equation.

So, isolating x from the first equation we have:

Then, substituting "x" into the second equation, we have:

Therefore, substituting "y" into the first equation, we have:

So, the solutions for the system of equation are:

Have a nice day!

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
