Equations in Standard Form

Rewrite the equation into Standard form

• 5x + 8y = 56

• -5x + 8y = 56

• 8x + 5y = 56

• 5x + y = 7

Jenny went to the sale at Kohl's last weekend.  
T-shirts were on sale for $15 each and hoodies were on sale for $20 each.  If she spent $150 total, write an equation to represent this situation.  

• 20x + 15 = y 

• 35x = y 

• 15x + 20y = 150 

• 150 - 20x = 15y
