x=-8

Step-by-step explanation:

First you should add 5x+67 and 5x+61 together which is 10x+128

Then you set that equal to 3x+72 which would be: 10x+128=3x+72

After that subtract 3x from both sides which leaves you with: 7x+128=72

Then subtract 128 from 72 which gives you: 7x=-56

Then divide by 7 which gives you x equals negative eight

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
