Question

7n+6n-5=4n+4
Show work.

Answer 1

Combine like terms,

7n + 6n = 13n

13n - 5 = 4n + 4

Add both sides 5

13n - 5 = 4n + 4
+5 +5

13n = 4n + 9

Subtract 4n from both sides

13n = 4n +9
-4n -4n

9n = 9
/9 /9

n = 1

Answer 2

This is a true statement because ,

7(1) + 6(1) - 5 = 4(1) + 4

7 + 6 - 5 = 4 + 4

13 - 5 = 8

4 +4 = 8

8 = 8 <-- true
