30x-21=5\left(x+2\right)
Multiply both sides of the equation by 15, the least common multiple of 5,3.
30x-21=5x+10
Use the distributive property to multiply 5 by x+2.
30x-21-5x=10
Subtract 5x from both sides.
25x-21=10
Combine 30x and -5x to get 25x.
25x=10+21
Add 21 to both sides.
25x=31
Add 10 and 21 to get 31.
x=\frac{31}{25}
Divide both sides by 25.
