Let the length of silk be x metre
Therefore the length of cotton = 3x-7 metres
The required equation is
x+3x-7=193
Solution
x+3x-7=193
4x=193+7
x=200/4
x=50 metres
The length of silk = 50 metres
The length of cotton = 3*50-7
= 143 metres
Therefore the length of cotton = 3x-7 metres
The required equation is
x+3x-7=193
Solution
x+3x-7=193
4x=193+7
x=200/4
x=50 metres
The length of silk = 50 metres
The length of cotton = 3*50-7
= 143 metres
