23 + 5u = 17Subtract 17 23 from both sides:5u = -6Divide both sides by 5:u = -6/5
Do you mean 5u-10 = u+46? If so then:- 5u-10 = u+46 5u-u = 46+10 4u = 56 u = 14
24uv + 35u2 - 30u3 - 28v = 24uv - 28v - 30u3 + 35u2 = 4v*(6u - 7) - 5u2(6u - 7) = (4v - 5u2)*(6u - 7)
There are an infinite number of possible answers - there are an infinite number of formulae that can be found to give t{1..5} = {12, 59, 294, 1469, 7344} which will give different values for t8. eg: t{n} = (376n⁴ - 3384n³ + 11186n² - 15369n + 7227)/3 gives t{1..5} = {12, 59, 294, 1469, 7344}, and t8 = 135889. t{n} = (-4929n⁵ + 76943n⁴ - 446037n³ +1198513n² -1473498n + 649296)/24 also gives t{1..5} = {12, 59, 294, 1469, 7344}, but t8 = -381656. However, the solution your teacher is probably expecting is based on the fact that: U1 = 12 U{n} = 5U{n-1} - 1 for n ≥ 2 This leads to: t1 = 12 t{n} = 12 + 47 × 5ⁿ⁻² for n ≥ 2 → t8 = 917969
5u + 2 = -185u = -20u = -4
-5u + 4 + 8u = 43simplify by subtracting 4 from both sides of the equation to get rid of the 4 on the left:-5u + 8u = 43Simplify further by combining the -5u and the 8u:3u = 43Divide both sides by 3 to solve for u:u = 43/3rewrite the fraction:u = 14 1/3
23 + 5u = 17Subtract 17 23 from both sides:5u = -6Divide both sides by 5:u = -6/5
Do you mean 5u-10 = u+46? If so then:- 5u-10 = u+46 5u-u = 46+10 4u = 56 u = 14
If you mean: 5u+10 = u+46 Then the value of u is 9
in the question 7-5u=-43, the answer to u is -45, because 7-5=2, 2x-45=-43. so u=-43.
6t -2t + 5u = 4t - 5u
2u + 1 = 5u + 5 2u - 5u = 5 - 1 -3u = 4 3u = -4 u = -4/3
- 29 = - 4 = 5uadd 4 to each side- 29 + 4 = - 4 + 4 + 5u- 25 = 5udivide both sides integers by 5- 25/5 = (5/5)u- 5 = u========check in original equation- 29 = - 4 + 5(- 5)- 29 = - 4 - 25- 29 = - 4 + (- 25)- 29 = - 29=============checks
3u - 5u= - 2u=====
No. It is a sum of four terms which can be simplified to a sum of three terms.
