8x + 7 = 5x + 28 subtract 5x and 7 to both sides
3x = 21 divide by 3 to both sides
x = 7
Take the square root of both sides of the equation
Multiply by 4
In the equation "you = mgh", divide both sides of the equation by mg, or you/mg = mgh/mg. The answer then is h = you/mg.
Subtract two from both sides and you are left with X equals -5

Take the square root of both sides of the equation
To solve for y, divide both sides of the equation by -0.8.
Divide both sides by 100 n = 3
Divide both sides of the equation by 12: x = 2
Multiply by 4
In the equation "you = mgh", divide both sides of the equation by mg, or you/mg = mgh/mg. The answer then is h = you/mg.
Subtract two from both sides and you are left with X equals -5
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
0.25n = 4 Divide both sides by 0.25:- n = 16
