Hello Friend, the answer for your question is given below.
1) 15y/4 = 5/8
15y = 5/8*4 (multiply 4 with 5/8)
15y = 5/2 (in simplified form)
y =5/2 whole divided by 15
take reciprocal of 15 to multiply
y = 5/2*1/15
Therefore y = 1/6
2) 2(x + 7) + 6 = -8
2(x + 7) = -8 -6
2(x + 7) = -14
x + 7 = -14/2
x + 7 = -7
Therefore x = -7-7
x = -14
Hope these answers help you.
