Slope is found by this form. Y = mX + c ( m = slope ) - 5X - 7Y - 6 = 0 ( I assume this is what you mean ) - 7Y - 6 = 5X - 7Y = 5X + 6 Y = - 5/7X - 6/7 The slope would be in this instance, - 5/7 ----------
8x-7 plus 2x equals 6 plus 5x plus 2?
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33
5x + 6 = -44 ⇒ 5x = -50 (subtract 6 from both sides) ⇒ x = -10 (divide both side by 5)
6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
10x-7y = -6 5x+7y = 81 Add both equations to eliminate y: 15x = 75 Divide both sides by 15 to find the value of x: x = 5 Substitute the value of x into the original equations to find the value of y: Therefore: x = 5 and y = 8
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7

8x-7 plus 2x equals 6 plus 5x plus 2?
x=6
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
Substitute the values of x and y in 10x + 7y, thus: 10x + 7y = 10*9 + 7*6 = 90 + 42 = 132
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
y is the variable
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
