Step-by-step explanation:
Answer:
Kelly collected 114 pounds of newspaper. Rachel collected 79 pounds of newspaper.
Step-by-step explanation:
Write an expression for each girl to figure out how many pounds of newspapers they each collected:
(x represents pounds of newspapers) Rachel = x Kelly = x + 35
To solve, combine the two expressions into one equation: 2x + 35 = 193
Then, subtract 35 from both sides of the equation. Make sure you subtract from both sides of the equation to keep it equal: 2x + 35 - 35 = 193 - 35
The equation left is: 2x = 158
Divide both sides by two in order to get the x by itself: 2x ÷ 2 = 158 ÷ 2
The answer will be: x = 79
Then, substitute 79 for x in the first equations:
Rachel = 79 Kelly = 79 + 35
Solve for the final answer: Rachel = 79 Kelly = 114
