1+x\times 3=4x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
1+x\times 3-4x=0
Subtract 4x from both sides.
1-x=0
Combine x\times 3 and -4x to get -x.
-x=-1
Subtract 1 from both sides. Anything subtracted from zero gives its negation.
x=1
Multiply both sides by -1.
