x=2 because 9-(14)=-5

7x - 9y = -63.When y = 0 then the resultant answer provides the x intercept.7x - 0 = -63 : x = -9When x = 0 then the resultant answer provides the y intercept.0 - 9y = -63 : y = 7Alternatively, to ascertain the y intercept convert the equation into the form y = mx + c, c is the y intercept.7x - 9y = -63 : -9y = -7x -63 : 9y = 7x + 63 : y = 7/9x + 7

x=6

x=6

7(x + 3)(x - 3)

-2x + 8 = 7x - 10 is technically an equation, in and of itself.

If you mean 5x^2 -7x +2 = 0 then it is a quadratic equation with solutions of x = 2/5 or x = 1

63

-7 is.

9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)

4x - 7 = 5 + 7x x = -4

yes.

7x - 12y = any other number.

7x=42 x=42/7 or, x=6

7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8

It is -7

Im guessing that the equation is 7x - 2y +3z= 19 so the answer is 7x + 3z= 19

7x + 9 = 51 7x = 42 x = 42/7 = 6

3x-8=7x+10x 3x-8=17x -8 = 14x -4=7x -4/7

7x = -3y + 12

If the equation is 7x - 3y = 21 then (3, 0) and (0, -7).

(7x + 8)(7x - 9)

When factored it is: (7x+8)(7x-9)

Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
