Write an equation for the following word problem.

Isaiah had to design a profit generating activity. He decided to make homemade brownies.  
The supplies cost $11.00 
and he wanted to pay himself $15.00 for the time it took to make the brownies. 
If the brownies were sold for $2.00 each, what equation will show his profit?
​ (a)   +​ (b)   =​ (c)  

• -26
• 2x
• Total profit (or y)
• -15
• -11
• -2x

• h=4

• divide both sides by the coefficient

• You must isolate h

• Subtract 9 from both sides

• Zero out the number from the OTHER side

• Distribute -2 and 5

• Zero out the variable on one side

• Combine like terms on each side

• Divide by the coefficient of m
