Answer 1

\[\frac{ x+y }{ 2 }+\frac{ x-7 }{ 2 }=7\]
\[x=\frac{ y }{ 2 }+6\]

Solve the system of equations

Answer 2

solve by addition.

Answer 3

First thing is to clean up the first equation a bit. Notice that both of the fractions have a common denominator, which means you can combine them.

Answer 4

(x+y)/2 + (x−7)/2 = 7

x/2 +y/2 +x/2 -7/2 = 7

x + y/2 -7/2 = 7

a) x + y/2 = 10.5
b) x - y/2 = -6
Can you solve it from there?
