The expression (3n + 4n - 14) simplifies to (7n - 14) by combining the like terms (3n) and (4n). This represents a linear expression in terms of (n).
3n + 4n = -14 7n /7 = -14 /7 n = -2
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
To solve the equation (3n - 2 = 4(n + 3)), start by distributing the 4 on the right side: (3n - 2 = 4n + 12). Rearranging gives (3n - 4n = 12 + 2), which simplifies to (-n = 14). Thus, (n = -14).
The expression "4n 12 3n - 3" seems to be missing some operators. Assuming you meant "4n + 12 + 3n - 3," you can combine like terms. This simplifies to (4n + 3n) + (12 - 3), resulting in 7n + 9. If the intended expression is different, please clarify.
4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True
3n + 4n = -14 7n /7 = -14 /7 n = -2
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
-n + 4n = 4n - n = 3n Done!!!!!
If you mean: n-3n = 14-4n then n = 7
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
The expression "4n 12 3n - 3" seems to be missing some operators. Assuming you meant "4n + 12 + 3n - 3," you can combine like terms. This simplifies to (4n + 3n) + (12 - 3), resulting in 7n + 9. If the intended expression is different, please clarify.
4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True
3n + 4n = 42 7n = 42 n = 42/7 n = 6
3 + 3n = 9 + 2n + 4n n = -2
It is 12n2 + 3n - 58
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
