3a+5b+7a=
-7a + 3a = -4a
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
To simplify the expression 6a^2 - 6ab + 7a^2, first combine like terms. Combine the terms with the same variable (a) raised to the same power. This results in 13a^2 - 6ab as the simplified expression. Remember to keep the terms in standard form with the variable term first, followed by any constant terms.
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.

It seems like the question is incomplete, but assuming you meant to ask "What does 6a plus a equal?" In that case, the answer would be 7a, as you are combining like terms by adding the coefficients of the variables. The expression simplifies to 7a because 6a + a = 7a.
7a+a=8a
The relevant expression is 7a.
7a
The expression ( 7a - a - a - a - a ) simplifies by combining like terms. You can group the ( a ) terms together: ( 7a - 4a ), which results in ( 3a ). Therefore, the simplified expression is ( 3a ).
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
3a+5b+7a=
To solve the expression (7a + 4b - 1), you typically need to know the values of (a) and (b). Once you have those values, you can substitute them into the expression and perform the arithmetic to find the result. If no specific values are given for (a) and (b), the expression remains in its simplified form.
