The equation is x + 14 = 25.
Apply subtraction property of equality: Subtract 14 from each side.
x + 14 14 = 25 14
x + 0= 25 14 (Apply additive inverse property: 1414 = 0)
x = 25 14 (Apply additive identity property: x + 0 = x)
x = 11 (Subtract: 2514 = 11)
Check:
To check the solution, substitute x = 11 in original equation.
x + 14 = 25 11 + 14 = 15
25 = 25 (Add: 11 + 14 = 25)
The statement is true.
Graph the solution on number line.
- First draw a number line.
- Mark a dot at 11 on the number line.
The value of x = 11.
