1-step equation (inequality)
Requires only one operation to solve the equation 7+x=21 or 2x=24
A one-step equation (inequality) is a mathematical expression that can be solved in a single step. It typically involves one variable and a single operation, such as addition, subtraction, multiplication, or division.
One example of a one-step inequality that can be solved in a single step is:
2x + 5 ≤ 13
To solve this inequality, we can start by isolating the variable term on one side of the equation:
2x ≤ 13 – 5
2x ≤ 8
Then we can divide both sides of the inequality by the coefficient of x:
x ≤ 4
So the solution to this inequality is that x is less than or equal to 4.
