2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
7-2n=n-147-2n+2n=n-14+2n7=3n-147+14=3n21=3n21/3=3n/37=n
if you mean 2n=8, then N=4, which translate to 2x4=8
2(4) = 8
-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13
2n plus 7 equals 19 2n equals 12 n equals 6
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
7-2n=n-147-2n+2n=n-14+2n7=3n-147+14=3n21=3n21/3=3n/37=n
if you mean 2n=8, then N=4, which translate to 2x4=8
2(4) = 8
-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13
3n+5=2n+7 subtract 2n on both sides. n+5=7 subtract 5 to the other side. n=2 the answer to n is 2. Hoped that helped. (:
20-2n when n = 7. just take 20-2(7) replace n with 7. then use the PEMDAS rule. 2(7) = 14, then 20-14 = 6
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
n=-9.6
