Answer 2

I can help you solve the system of equations by the method of addition. Here are the steps:

1. Rewrite the system in the standard form: $$3x-12y=-2$$ $$2x+y=27$$ 2. Multiply the second equation by 12 to eliminate the y-term: $$3x-12y=-2$$ $$24x+12y=324$$ 3. Add the two equations and solve for x: $$27x=322$$ $$x=\frac{322}{27}$$ 4. Substitute the value of x into one of the original equations and solve for y: $$2\left(\frac{322}{27}\right)+y=27$$ $$y=27-2\left(\frac{322}{27}\right)$$ $$y=\frac{27}{2}$$ 5. The solution is $$\left(\frac{322}{27},\frac{27}{2}\right)$$
