Answer 1

Answer:

660/153

Step-by-step explanation:

$3(5x - 2) + 0.30x = 60 \\ 15x - 6 + 0.30x = 60 \\ 15.30x = 66 \\ x = 6600 \div 1530$

660/153

Answer 2

3(5n - 2) + 30% of n = 60

15n - 6 + 30/100 * n = 60

15n - 6 + 0.3 n = 60

15n - 0.3n = 60 + 6

14.7n = 66

n = 66/14.7

n = 4.49(approx)
