Using the equation x – 3y = -21, create a system of equations that can be easily solved using the addition method. Include the system you created, your solution methods, and your final answer.

I AM WEAK IN MATHEMATICS

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
