Solution:

1) Cancel 7 on both sides
x\times 0.04=x\times 4x

2) Regroup terms
0.04x=x\times 4x

3) Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}
​​
0.04x={x}^{2}\times 4

4) Regroup terms
0.04x=4{x}^{2}
​​
5) Move all terms to one side
0.04x-4{x}^{2}=0

6) Factor out the common term xx
x(0.04-4x)=0

7) Solve for x
x=0,0.01

Done!
