14x = 7y+28 -7y = -14x+28 Divide all terms by -7 to find the value of y: y = 2x-4 which is now in slope intercept form
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
7y + 18 = 39 Therefore, 7y = 39 - 18 = 21 y = 21/7 y = 3
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
14x = 7y+28 -7y = -14x+28 Divide all terms by -7 to find the value of y: y = 2x-4 which is now in slope intercept form

x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
-14x-7 = 35 -14x = 35+7 -14x = 42 x = -3
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
7y + 18 = 39 Therefore, 7y = 39 - 18 = 21 y = 21/7 y = 3
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
If: -14x = -98 Then: x = 7
49 x2 + 14x = -7 x2 + 14x + 49 = 42 (x + 7)2 = 42 x = -7 ± √42
