Answer:

Your answer is in the screenshot! :)

Step-by-step explanation:

1. Solve for yy in y+7x=50y+7x=50. y=50-7x

y=50−7x

2. Substitute y=50-7xy=50−7x into 14x-5y=-2814x−5y=−28. 49x-250=-28

49x−250=−28

3. Solve for xx in 49x-250=-2849x−250=−28. x=\frac{222}{49}

x= 49 222 ​

4. Substitute x=\frac{222}{49}x= 49 222 ​ into y=50-7xy=50−7x.

y=\frac{128}{7} y= 7 128 ​

5. Therefore, \begin{aligned}&x=\frac{222}{49}\\&y=\frac{128}{7}\end{aligned} ​ x= 49 222 ​ y= 7 128 ​ ​Hope this helped!! :))
