It is 2 - 7 = -5
im assuming your equation is 2x + 1 = 7 in this case you need to find what x equals 2x + 1 = 7 2x + 1 - 1 = 7-1 2x = 6 x = 3 put it back into the equation to check if your answer is correct 2(3) + 1 = 7 6 + 1 = 7 7 = 7 Correct! if your equation is 2x - 1 = 7 x = 4 check it 2(4) - 1 = 7 8 - 1 = 7 7 = 7 Correct! if your equation is 2x1 = 7 x = 7/2 check it 2(7/2)1 = 7 2(7/2) = 7 2 * 7 / 2 = 7 14/2 = 7 7 = 7 Correct! hope i got your equation right. if not you can message me on my message board to get more help.
Equation of the circle: (x-7)^2 +(y-7)^2 = 49
depends on the equation.
It seems that the equation you provided is not clear. "x - 2 5 and 7 equal 2 and 3" doesn't form a valid equation. If you can provide a clearer equation, I can help you solve it.
x/7 = 2 Multiply both sides by '7' 7x/7 = 7 x 2 = 14 On LHS cancel down '7' Hence x = 14

7-2 IS positive. You do not need an equation for it. And if it were not positive, no correct equation would show it to be positive.
Equation of the circle: (x-7)^2 +(y-7)^2 = 49
If you mean points (7, 2) and (0, 0) then the slope is 2/7 and equation is y = 2/7x
depends on the equation.

Equation of circle: (x-2)^2 +(y+9)^2 = 49
x/7 = 2 Multiply both sides by '7' 7x/7 = 7 x 2 = 14 On LHS cancel down '7' Hence x = 14
Centre of the circle is at (7, 7) and its Cartesian equation is (x-7)^2 + (y-7)^2 = 49
Points: (1, 5) and (2, 7) Slope: 2 Equation: y = 2x+3
