To write the inverse, you replace negatives with positives (and vice versa). Thus, for -3x + 5, it would be 3x - 5.
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
If: 8x-4 = 3x+21 Then: 8x-3x = 21+4 => 5x = 25 => x = 25/5 Therefore: x = 5
This is only half of an equation. If -x^2 + 3x +2y = 0, then x^2 -3x = 2y and y = (x^2-3x)/2 Solving for x is the inverse, but difficult without a second equation.
x = 4
To write the inverse, you replace negatives with positives (and vice versa). Thus, for -3x + 5, it would be 3x - 5.
y = 3x + 2 y-2 = 3x x = (y-2)/3 So the inverse is (x-2)/3
If you mean: y-2 = 3x+2 then as a straight line equation it is y = 3x+4
f(x) = 3x + 9 y = 3x + 9 so 3x = y - 9 x = y/3 - 3 Therefore, the inverse function is g(x) = x/3 - 3
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
-3x + 10x - 5 + 26 = 7x + 21
If: 8x-4 = 3x+21 Then: 8x-3x = 21+4 => 5x = 25 => x = 25/5 Therefore: x = 5
This is only half of an equation. If -x^2 + 3x +2y = 0, then x^2 -3x = 2y and y = (x^2-3x)/2 Solving for x is the inverse, but difficult without a second equation.

21-7y+3x-xy7(3-y)+x(3-y)

3x2 + 2x - 21 = (3x - 7) (x + 3)
