n - 16 = 2n + 12 + 3nCombine the 'n' terms on the right side:n - 16 = 5n + 12Subtract 'n' from each side:-16 = 4n + 12Subtract 12 from each side:-28 = 4nDivide each side by 4:-7 = n
How do you work out 7n plus 1 equals 6n plus 8?
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
Why is plus multiplied by minus minus?
Imagine the number line. Suppose on the left it starts -6, -5, -4, -3, -2, -1, 0, +1, +2, +3, etc. Let's calculate 2 x (-3). The expression -3 says starting at zero, go left 3 steps. The expression 2 x means do it twice. Where do you finish? -6 If you see why you finish on the left side, you have your answer. What about minus x minus. Let's calculate (-2) x (-3). Again -3 says starting at zero go left 3 steps. The expression -2 x means, no, go the other way instead -- twice. Where do you finish? +6. Minus x minus = plus.
5n minus 9 equals 2n plus 6?
Subtract 2n from each side: 3n - 9 = 6 Add 9 to each side: 3n = 15 Divide both sides by 3: n = 5 Therefore, n = 5
