$\star{ \sf{ \: x - 15 = 40}}$

$\text{Step \: 1 \: : Move \: 15 \: to \: right \: hand \: side \: and \: change \: its \: sign}$

$\mapsto{ \sf{x = 40 + 15}}$

$\text{Step \: 2 \: : Add \: the \: numbers : 40 \: and \: 15}$

$\mapsto{ \boxed {\sf{ {x = 55}}}}$

Solve this r/6=5 2/3

myrzilka [38]

First, incorporate the 5 into the 2/3 fraction by multiplying the 5 by the 3 and then adding that quantity by the 2, which now makes the fraction:
17/3
Now set it up with the equation:
r/6 = 17/3
r/6×3 = 17/3×3
r/3 = 17
r/3×3 = 17×3
r = 51
