Question 138883
1/6(y+42)-15=-3
:
Add 15 to both sides:
{{{1/6}}}(y+42) = 15 - 3
{{{1/6}}}(y+42) = 12
:
Multiply both sides by 6:
y + 42 = 6(12)
y + 42 = 72
:
Subtract 42 from both sides:
y = 72 - 42
y = 30
:
:
Check solution in original equation:
{{{1/6}}}(30+42) - 15 = -3
{{{1/6}}}(72) - 15 = -3
 12 - 15 = -3; confirms our solution
