\[\frac{ x2 }{ 3 } + \frac{ y+1 }{ 5 } = 2\]
\[\frac{ x+2 }{ 7 }  \frac{ y+5 }{ 3 } = 2\]

first get rid of the fractions by multiplying each equation by the LCM of the 2 denominators
which is 15 and 21 as mathstudent55 stated

now simplify it further:
5x  10 + 3y + 3 = 30
5x + 3y = 30 + 10  3
5x + 3y = 37
