1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
i dont know
25x2-49y2 is the difference of two squares and can be factored as:- (5x-7y)(5x+7y)
The simplified expression is 3x - 7y.
-5x+7y-6z
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
5x - 7y = 5 (subtract both sides by 5x) -7y = -5x + 5 (divide both sides by -7) y = (5x - 5)/7 If you want to solve for y = 0, then x = 1.
5x - 7y = -35At the x-intercept, y=0:5x = -35x = -7At the y-intercept, x=0:-7y = -35y = 5
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 ----------
5x = 7y , we divide both side by 'y' 5x/y = 7y/y (y will now be deducted) 5x/y = 7 x/y = 7/5 Therefore, x:y = 7:5

25x2-49y2 is the difference of two squares and can be factored as:- (5x-7y)(5x+7y)
The simplified expression is 3x - 7y.
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
