50+9.50x=240
9.50x=190
X=20
20 hours last week
First you are given $50 this will not change and he makes 9.50 per hour so 9.50x because x is the amount of hours he works and what you need to solve for
To solve get x by itself start by getting rid of things without the variable (x)
So take 50 and subtract it from both sides
Then you’re left with 9.50x= 90
Go get rid of the 9.50 since it’s attached to x you’ll divide both sides by 9.50 which gives you x=20
