Hey there!
“3r = 10 + 5s”
“r = 10”
3(10) = 10 + 5s
3(10) = 30
30 = 10 + 5s
“30 = 10 + 5s”
• FIRST: REVERSE/FLIP the EQUATION
5s + 10 = 30
• SECOND: SUBTRACT by 10 on BOTH SIDES
5s + 10 – 10 = 30 – 10
CANCEL: 10 – 10 because It gives you 0
KEEP: 30 – 10 because that helps us solve for our “s-value”
“30 – 10 = 20”
NEW EQUATION: 5s = 20
• THIRD: DIVIDE both SIDES by 5
5s/5 = 20/5
CANCEL out: 5/5 because that gives you 1
KEEP: 20/5 because that helps us solve for our “s”
NEW EQUATION: 20/5 = s
SOLVE ABOVE and YOU HAVE YOUR “S”
20/5 = 4
Answer: s = 4 ☑️
Good luck on your assignment and enjoy your day!
