Question

Name the property illustrated By if 3x + 4y = 6 and x = 5 then 3(5) + 4y = 6

Answer 1

Substitution property of equality

Explanation:

Given

`3x + 4y = 6`

`x = 5`

`3(5) + 4y = 6`

Required

Name the property used

From the question, we have that:
`x = 5`

This implies that 5 can be substituted for x in the given equation
`3x + 4y = 6`

So, when 5 is substituted for x, we have that:

`3(5) + 4y = 6`

Conclusively, the property that was applies is the Substitution property of equality
