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
To solve an equation using inverse operations, you apply operations that "undo" the effects of the current operations in the equation. For example, if the equation involves addition, you subtract the same number from both sides; if it involves multiplication, you divide both sides by the same number. This process isolates the variable, allowing you to find its value. By systematically applying inverse operations, you maintain the equality of the equation while simplifying it.
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
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.
A 2-step equation that equals 13 could be: 2x + 7 = 13. To solve this equation, first subtract 7 from both sides to isolate the variable: 2x = 6. Then, divide both sides by 2 to solve for x: x = 3. Therefore, when x = 3, the equation 2x + 7 equals 13.
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
