Ill give brainliest solve this problem using the elimination method. x + y = 21 2x + 3y = 47

x = 16, y = 5

Step-by-step explanation:

Let's eliminate a variable first. In this case, I multiplied the first equation by -2 so that I could get rid of x and solve for y. This is how it looks like:

-2x - 2y = -42

2x + 3y = 47

Combine both these equations and you get y = 5, so you solved for y already!

Now you have to solve for x. Let's use your first equation to do that.

x + y = 21

x + 5 = 21

x = 16

Hope this helps!

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

∠cbe and ∠deb are same-side interior angles.
