3x + 8x + 4x = 6x + 63
15x = 6x + 63
9x = 63
x = 7
so
5x + 23 = 5 (7) + 23 = 35+23 = 58

3x+8x+4x=6x+63
First, since almost everything is together, combine like terms
15x=6x+63
Now, subtract 6x from both sides
9x=63
Now divide both side by 9
x=7
Now that we have found what x equals, we need to plug in the variable into 5x+23
5 (7) + 23
Now just simplify
35+23 = 58
Therefore, 5x+23 when x=7 is 58
