Answers
Answer:
7.) 80/7
8.) 77/19
9.) 13/12
I've doubt in 9th one rest are correct ig....
Step-by-step explanation:
7.) 12/7(q-5) = 24 + 8q
→ 12/7q - 60/7 = 24 + 8q
→ ( Combining the like terms, we get)
→ 12/7q - 8q = 24 + 60/7
→ 12-8/7q = 24+60/7
→ 4/7q = 84/7
→ q = 84/7 - 4/7
→ q = 80/7
Answer = 80/7 or 11whole3/7
8.) s-8/3 = 7-4s/7
→ (Cross multiply, we get)
→ 7s - 56 = 21 - 12s
→ (Combining like terms, we get)
→ 7s + 12s = 21 + 56
→ 19s = 77
→ s = 77/19
Answer = 77/19 or 4whole1/19
9.) 2y - 3/4 - 2y - 1/ 3 = 1
→ LCM of 3 and 4 = 12
[→ 2y-3×3/4×3 = 6y-9/12]
[→ 2y-1×3/3×4 = 6y-3/12]
→ 6y-9/12 - 6y-3/12 = 1
→ 6y-9 - 6y-3/12 = 1
→ (Combine like terms and subtract, we get)
→ 6y-6y-9-3/12 = 1
→ y - 12/12 = 1
→ y = 1 + 12/12
→ y = 1 + 12/12
→ y = 13/12
Answer = 13/12 or 1whole1/12
