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!

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
