7y+ 8x + 4= 20 + 8x
- 8x - 8x
7y + 4 = 20
- 4 - 4
7y=16
/7 /7
y= 2.28
the /7 means divide by 7 :)
-8x-6y=-18
no its not a solution
-8x -7y
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
8x - 7y + 2 = 0 The slope-intercept form is NOT the standard form. The above form is easily generalised to 3 (or more) dimensions, not so with the slope-intercept form.
-8x-6y=-18
no its not a solution
(3,7)
-8x - 10 - 20 = -8x - 30
-8x -7y
The lines intersect at (3, 5)
8 over 7.
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
Y-8x plus 9y equals 10y-8x.
8x - 7y + 2 = 0 The slope-intercept form is NOT the standard form. The above form is easily generalised to 3 (or more) dimensions, not so with the slope-intercept form.
