10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4
An algebraic expression
10n = 80.n = 8.
If: 10n = 1,000,000 Then: n = 100,000
5n - 4 = 10n + 6-5n = 10n = -2
10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4
10n + 3 = 7n + 53n = 2n = 2/3
An algebraic expression
5m+n = 37 m-2n = 14 => m = 2n+14 Substitute the value of m into the top equation: 5(2n+14)+n = 37 10n+70+n = 37 10n+n = 37-70 11n = -33 Divide both sides by 11 to find the value of n: n = -3 Substitute the value of n into the original equations to find the value of m: Therefore: n = -3 and m = 8
The resultant force on the system of forces 2N and 8N acting in the same direction is 10N (2N + 8N).
10n = 80.n = 8.
dont blimmin care

If: 10n = 1,000,000 Then: n = 100,000
18Letn = the number to be multiplied to 2Equation:n * 2 = 36dividing the equation by 2:2n/2 = 36/2n = 18
2n+2n equals 4n
5n - 4 = 10n + 6-5n = 10n = -2
