7x-5=0
7x=5
x=5/7
Your answer was wrong. When you transpose (shift) the -5 to right side the sign should change and become a positive 5.
I don’t know if that makes sense.
In maths, when you move a number over the equal sign whether it’s to the right or the left of the equal sign the sign infront if the number must change as well.
Example:
2x +4=0
2x= -4
x=-2
