4x-5y+20 = 0
-5y = -4x-20
y = 4/5x+4 which is now in slope intercept form
To solve for x, we'd have to know what this expression equals.
y=16 x= -4
-7m + 20 = -17m - 1010m = -30m = -3
-3x + 5 = 20 -3x = 15 x = -5
4m+15=8m-5 or,4m=20 or,m=5
(20 - x)/5
20
To solve for x, we'd have to know what this expression equals.
y=16 x= -4
-7m + 20 = -17m - 1010m = -30m = -3
68
-3x + 5 = 20 -3x = 15 x = -5
Better formatting is cos(2x+20)=-0.5
20 = 400
balance the equation 3x-x=20-6 3x-x=2x 20-6=14 2x=14 x=7
3x^2=-20 so x^2=-20/3 this has no real roots but the plus of minus i(square root of 20/3) is a solution if we allow complex numbers.
To solve the equation 8 plus what equals 20, we need to find the missing addend. We can do this by subtracting 8 from 20, which equals 12. Therefore, 8 plus 12 equals 20.
