Let's translate the words into expressions:
11 less than 7 times a number is
5 more than 6 times the number is
So we have the equation
Subtract 6x from both sides:
Add 11 to both sides:
Answer:
It might help you if you knew what variable was.
A variable can be (x) or (y) or anything really it just a letter the represents a number.
In this case, when it says solve for a variable it means find what the variable equals. For example:
4x + 18 = 2
here you need to find the value of X.
x = -5
X equals negative 5 because you multiply the variable to the number:
4 x -5 = -20
-20 + 18 = 2
making the answer:
4(-5) + 18 = 2
x = -5

The answer is 180 hope this helps
