Module 8 Review

Two brothers went shopping at a back-to-school sale where all shirts and shorts were the same price. The younger brother spent $175 on 7 new shirts and 7 pairs of shorts. The older brother purchased 6 new shirts and 7 pairs of shorts and paid a total of $165. Write the system of equations. 

• 7x+7y=165
  7x+6y=175
• 7x+7y=175
  7x+6y=165
• 7x+7y=175
• 7x+6y=165

What is the easiest method to solve with? 
2x - 2y = 2
y = -5x + 14

When eliminating, what would be the first step?
x - 2y = 2
3x + 4y = 3

• multiply top by -3 
  or
  multiply top by 2
• multiply bottom by 1
• cross out the x's
• cross out the y's
