2 students to the study group. How many total students are invited to the study group?
The final expression after combining like terms is 2r + 2.
We are given that;
The expression 8r+7−6r−5
Now,
According to the search results, combining like terms is a common technique for simplifying algebraic expressions. Like terms are terms that have the same variable and exponent.
To combine like terms, simply add or subtract their coefficients and keep the common variable part.
The coefficient is the number that appears in front of the variable.
In given expression, 8r+7−6r−5, there are two like terms: 8r and -6r.
They have the same variable r and exponent .
To combine them, we add their coefficients: 8 + (-6) = 2.
We keep the common variable part r.
So, 8r - 6r = 2r.
The other two terms, 7 and -5, are also like terms.
They are constants with no variables.
To combine them, we add their coefficients: 7 + (-5) = 2.
So, 7 - 5 = 2.
Therefore, by algebra the answer will be 2r + 2.

Paula should have solved for x. So 7+x=10 would be
-7 -7
X=3 to check7+3=10
10=10
