5г + 8 < 63 =

I think there is an error in the equation you provided. There is an extra "=" sign, which is not needed.

Assuming the equation is actually:
5g + 8 < 63

Here's how to solve it:

1. Subtract 8 from both sides of the inequality:

5g < 55

2. Divide both sides of the inequality by 5:

g < 11

So the solution to the inequality is g < 11.
