Question

Use the eliminatio method to solve the system of equations. Choose the correct order pair: 3x+5y=48 -3x+5y=12

Answer 1

Answer:

(6,6)

Step-by-step explanation:

3x+5y=48

-3x+5y=12

Ok so when you're doing elimination you want to combine all of the like terms. In this case, we need to combine 3x and -3x, 5y and 5y, and 48 and 12. 3x and -3x cancel out, so that leaves you with 10y=60. Solving for y gives you y=6. Now you need to solve for x, so using 3x+5y=48, by plugging in y you get 3x+(5*6)=48. Simplifying that gives you 3x+30=48. Subtract 30 and divide by 3, and you get x=6. Thus the Answer is (x,y) or (6,6)
