Answer:
Substitution property of equality
Step-by-step explanation:
Given
[tex]3x + 4y = 6[/tex]
[tex]x = 5[/tex]
[tex]3(5) + 4y = 6[/tex]
Required
Name the property used
From the question, we have that: [tex]x = 5[/tex]
This implies that 5 can be substituted for x in the given equation [tex]3x + 4y = 6[/tex]
So, when 5 is substituted for x, we have that:
[tex]3(5) + 4y = 6[/tex]
Conclusively, the property that was applies is the Substitution property of equality
