Question

help me solve the problem with step by step answers!!
1/3x=-x+4

Answer 1

1/3x=x+4
+x -x

1 1/3x=4
And then divide 4 by 1 1/3

Answer 2

1/3x=-x+4

Move -x to the other side.

Sign changes from -x to +x.

1/3x+x=-x+x+4

1/3x+x=4

Find the common denominator for x which is 3. Pretend that x is 1/1x

Multiply by 3 for 1/1x

1(3)/1(3)x=3/3x

1/3x+3/3x=4

4/3x=4

Multiply by 3/4 for both sides.

4/3(3/4)x=4(3/4)

Cross out 4 and 3, divide by 4 and 3 then becomes x

Cross out 4 and 4 , divide by 4 and then becomes 3

x=3

Answer: x=3
