To solve the equations, let's follow these steps:

1. X/17 = 12/51 + x To solve this equation, we need to find a common denominator for the fractions on the right side. The common denominator for 17 and 51 is 51. So, we can rewrite the equation as: X/17 = (12/51) * (51/51) + x Simplifying the right side gives us: X/17 = 12/51 + x/1 Now, we can combine the fractions on the right side: X/17 = (12 + 51x)/51 To isolate X, we can cross-multiply: 51X = 17(12 + 51x) Simplifying further: 51X = 204 + 867x Rearranging the equation: 867x - 51X = 204 Now, we can solve for X by dividing both sides of the equation by 51: X = 204/51 - 867x/51 Simplifying: X = 4 - 17x

2. 4/x = 20/90 + x To solve this equation, we need to find a common denominator for the fractions on the right side. The common denominator for x and 90 is 90x. So, we can rewrite the equation as: 4/x = (20/90) * (90x/90x) + x/1 Simplifying the right side gives us: 4/x = 20/90x + x/1 Now, we can combine the fractions on the right side: 4/x = (20 + 90x)/90x To isolate x, we can cross-multiply: 90x = 4(20 + 90x) Simplifying further: 90x = 80 + 360x Rearranging the equation: 360x - 90x = 80 Now, we can solve for x by dividing both sides of the equation by 270: x = 80/270 Simplifying: x = 8/27

So, the solutions to the given equations are: - X = 4 - 17x - x = 8/27
