Solve the equation X-5 of 12 = 5 of 730.4 △ (4-x) = 14.5 △ (x + 2) = 0.2 3x-4 times 6 = 4.8

Solve the equation X-5 of 12 = 5 of 730.4 △ (4-x) = 14.5 △ (x + 2) = 0.2 3x-4 times 6 = 4.8

X-12 / 5 = 73 / 5
X = 85 / 5
X=17
0.4÷（4-x）=14
4-X=0.4/14
X = 35 / 139
5÷（x+2)=0.2
X＋2＝25
X＝23
3x-4 times 6 = 4.8
3X-24=4.8
3X=28.8
X=9.6

How to solve the equation 3x-2 times 5 = 12

3x-2 times 5 = 12
3x-10=12
3x=10+12
3x=22
x=22÷3
X = 22 / 3

Solving equation 1 / 3x = (x + 6) × 4 / 9

1/3X+6=4/9(X+6)
1/3X+6=4/9X+8/3
6-8/3=4/9X-1/3X
10/3=1/9X
X=30
