How to solve the problem that x plus 3 / 3 x equals 12
X plus three parts of X is 12
Multiply both sides by 3 at the same time
3x+x=36
4x=36
x=36÷4
x=9

To solve the equation, x minus 50 percent, x equals 41, which is 6 out of 7 times 1 out of 11 plus 1 out of 7 divided by 11
（1）x-50x/100=41
x-x/2=41
x/2=41
x=82
（2）6/7*1/11+1/7÷11
=6/7*1/11+1/7*1/11
=1/11*（6/7+1/7）
=1/11
