3(x-5)+3x=4x+5 Multiply everything in () by 3
3x-15+3x=4x+5 Add the 3x and 3x
6x-15=4x+5 Add 15 to both sides
6x=4x+20 Subtract 4x from both sides
2x=20 Divide both sides by 2
x=10

3(x – 5) + 3x = 4x + 5?
3x - 15 + 3x = 4x + 5
6x - 15 = 4x + 5
6x = 4x + 20
2x = 20
x = 10
3(x - 5) = 3x - 15
Add like terms 3x + 3x giving you 6x.
Isolate the variable.
Add 15 to both sides.
Subtract 4x from both sides.
Divide by 2 from both sides.
Thus solving for x.

x=10
3(x-5) + 3x=4x + 5
3x-15 + 3x = 4x + 5
3x + 3x - 4x = 15 + 5
2x = 20
x=10
