The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to eliminate the yuvarlable, and what is the solution for this system? x+3y=42 2x-y= 14 ОА. Multiply the second equation by-3. The solution is x= 12, y=9. Multiply the second equation by-2. The solution is x=12, y=10. B. Ос. Multiply the second equation by 2. The solution is x= 15, y=9. D. Multiply the second equation by 3. The solution is x= 12, y=10.

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

Equation for the calculation double 2 and then add 5
