Consider the two properties that you would use to solve an equation like 3x + 5 = 26. Which of the following is true? The standa
gladu [14]
The subtraction property of equality: if we subtract one side of the equation then we also must subtract from the other side of the equation.
The division property of equality: if we divide one side of the equation by a number then we also must divide the other side by the same number.
For this equation:
3 x + 5 = 26
3 x + 5 - 5 = 26 - 5        ( the Subtraction Property of Equality )
3 x = 21
3 x : 3 = 21 : 3       ( the Division Property of Equality )
x = 7
Answer: C ) The standard method for solving an equation like 3 x + 5 = 26 is to use the Subtraction Property of Equality and then the Division Property of Equality.
