Transpose an equation.

Please help me to transpose this equation.

x/20 = (20-x)/15

Please solve for x.

I have the answer but its the steps I need.

Thank you.

x/20 = (20-x)/15
15x/20 = 20-x
3x/4 +x = 20
3x/4 +4x/4 = 20 Note, 4x/4 is the same as x so thats what i did here.
7x/4 = 20
7x = 80
x = 80/7 Which as a decimal is 11.4285714, or 11.429 to 3dp. and 11.4 to 3sf (depends what your teacher prefers)

x/20 = (20-x)/15

x = 20(20-x)/ 15

15x = 20(20-x)
15x = 400-20x

35x = 400
x = 400/35

x = 11
