State the property that justifies the statement: if 3x + 4 = 10, then 3x = 6
Subtraction Property of Equality
Addition Property of Equality
Division Property of Equality
Multiplication Property of Equality

Solution:

Given 3x + 4 = 10, then 3x = 6

Consider first equation 3x + 4 = 10

Subtract 4 on both sides

3x + 4 - 4 = 10 - 4

3x = 6

This is second equation

Hence, it is the subtraction property of equality.

State the property that justifies the statement: if 3x + 4 = 10, then 3x = 6

Summary:

It is subtraction property of equality which justifies the statement 3x + 4 = 10 then 3x = 6.
