Original equation: y = 3/4*x - 5
In order to find the inverse of an equation algebraically, you switch the 'x' and the 'y'.
1. y = 3/4*x -5 (original equation)
2. x = 3/4*y -5 (swap x and y)
3. x + 5 = 3/4 * y (add 5 to both sides)
4. 4/3(x + 5) = y (multiply both sides by the reciprocal of 3/4)
5. (4x + 20)/3 = y (simplify)
The inverse of y = 3/4*x - 5 is y = (4x + 20)/3.

How do you solve 0.5x minus5 equals x plus 4?
Multiply the whole thing by two. x - 10 = 2x + 8 Subtract x from both sides. -10 = x + 8 Subtract 8 from both sides. -18 = x Check it. -9 - 5 = -18 + 4 -14 = -14 It checks.
What is 3 times 3 plus 2 times 5 minus5 times 2 divided by 10 plus 5 divided by 5 equal?
If you were to put that in an algebraic expression, it would look like this:3 x 3 + 2 x 5 - 5 x 2 / 10 + 5 / 5 = Solution (Given that there are no parentheses)3 x 3 = 9+ 2=11X 5= 55- 5= 50X 2= 100/ 10= 10+ 5= 15/ 5= 3Therefore the answer is 3
