Answer:
Substitute
Step-by-step explanation:
Example
y=3
11+y=2x
The first thing you should do is put 3 in place of y in the second equation.
11+3=2x
14/2=2x/2
x=7
Simplifying
-1x + -7 = 5x + -11 + -7x
Reorder the terms
-7 + -1x = 5x + -11 + -7x
Reorder the terms
-7 + -1x = -11 + 5x + -7x
Combine like terms
5x + -7x = -2x
-7 + -1x = -11 + -2x
Solving
-7 + -1x = -11 + -2x
Whatever the frequency is, that's how many tally marks you put.
