Answer:

The answer is 2

Step-by-step explanation:

2 = 6 + 4n/ 7

cross multiplication

2 x 7 = 6 + 4n

14 = 6 + 4n

4n = 14 -6

4n = 8

n = 8 / 4

n = 2

These are all correct. To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one. Or just use a calculator lol.
