Question

What is the solution to the equation 5x+0.25=7x-0.05

Answer 1

5x + 0.25 = 7x - 0.05

substract 5x from both sides,
5x - 5x + 0.25= 7x - 5x - 0.05
0.25 = 2x - 0.05

substract -0.05 from both sides,
0.25 - (-0.05) = 2x - 0.05 - (-0.05)
0.25 + 0.05 = 2x - 0.05 + 0.05
0.30 = 2x

divide 2 from both sides,
0.30 / 2 = 2x / 2
0.15 = x

So, the solution is x = 0.15

Answer 2

the answer is : 0.15
