Hey there!
FIRST: you have to SIMPLIFY BOTH SIDES of your given EQUATION (there’s approximately 3 ways but we will use 2)
• 3u = 64 – 5u
• 3u = –5u + 64
SECOND: ADD by 5u on BOTH SIDES
• 3u + 5u = –5u + 64 + 5u
• CANCEL: –5u + 5u because that gives you 0
• KEEP: 3u + 5u because it can help us solve for you u-value
“3u + 5u = 8u”
New equation: 8u = 64
THIRD: DIVIDE by 8 on BOTH SIDES
• 8u/8 = 64/8
• CANCEL out: 8u/8 because that gives you 1
• KEEP: 64/8 because that gives you your u-value
“64/8 = u”
“64/8 = 8”
• Therefore your ANSWER: u = 8 ☑️
Good luck on your assignment and enjoy your day!
