.97=1 + (X/2,500,000)
1 - .97 = x/2,500,000
0,03 * 2,500,000 = x
x = 75,000
Solution: 75,000

Don't let the big numbers throw you
.97=1 + (X/2,500,000) subtract 1 from each side
-.03=x/2,500,000 multiply both sides by 2,500,000
x=-75,000

First: get rid of the fractions by taking the denominator (2,500,000) and multiplying it by everything in the equation:
(.97)(2,500,000) = 1(2,500,000) + (x/2,500,000)(2,500,000)
Second: multiply
2,425,000 = 2,500,000 + x
Third: solve for x by subtracting 2,500,000 from both sides:
2,425,000 - 2,500,000 = 2,500,000 - 2,500,000 + x
-75,000 = x; x= -75,000

You want to isolate x
.97 = 1 + (x / 2,500,000)
subtract 1 from both sides:
-.3 = x / 2,500,000
Now multiply by 2,500,000 on both sides to isolate x:
-.3 * 2,500,000 = x / 2,500,000 * 2,500,000
-750000 = x

.97 = 1 + (X/2,500,000)
Subtract 1 from both sides.
-.03 = (X/2,500,000)
Multiply both sides by 2,500,000
-75,000 = X
X = -75,000

(2,500,000).97 = 1 +(x/2,500,000)(2,500,000/1)
2,425,000 - 1 = x + 1 - 1
2,424,999 = x

x = -75,000
.97= 1+ (x/2,500,000) *get x by itself
-.03= (x/2,500,000) *mutiply 2,500,000
-75,000 = x
