3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1
If 9n = 36 then we divide both sides by 9 to discover what value n has If we divide 9n by 9 we get n If we divide 36 by 9 we get 4 so, if 9n = 36 the n = 4

7n = 7 divide by 7 on both sides n = 7

n * 4 = 80 Divide both sides by 4: n = 20
If you divide 4/7 it = 57.14 so your percentage is 57% that's an F
7n = 7 divide by 7 on both sides n = 7
(3n-2)/8 = (n+4)/55(3n - 2) = (n+4)815n - 10 = 8n + 327n = 42n = 6

4 divide by 7 = 0.5714285714285714
PEMDAS says to divide first then addSo64/4=1616+7=23
