See below.
Step-by-step explanation:
7x^2 = 343 Divide both sides by 7
7x^2/7 = 343/7

sqrt(x^2) = sqrt(49)
x = +/- 7

I think the last two are kind of iffy. I'm not sure you can call them solutions, but the question probably assumes they are. If you use all four answers and get it wrong, them submit +7 and - 7.
Answer:
85 and -31
step-by-step:
x + y = 54
x - y = 116
solve for x in first equation
x = 54 - y
sub into second equation
54 - y - y = 116
54 - 2y = 116
-2y = 62
y = -31
sub in x equation
x = 54 - (-31)
x = 85
