Answer 1

2а + 612 + 7а + 324 = 9а + 936
12у + 29у + 781 + 219 = 41у + 100

Answer 2

I can help you with simplifying algebraic expressions. Here is the answer to your question:

- To simplify an expression, you need to combine the like terms, which are the terms that have the same variable and the same exponent. - For example, 2a and 7a are like terms, because they both have the variable a and the exponent 1. You can add them together by adding their coefficients, which are the numbers in front of the variables. So, 2a + 7a = (2 + 7)a = 9a. - Similarly, 12y and 29y are like terms, because they both have the variable y and the exponent 1. You can add them together by adding their coefficients, which are 12 and 29. So, 12y + 29y = (12 + 29)y = 41y. - The numbers 612, 324, 781, and 219 are also like terms, because they have no variables and the same exponent 0. You can add them together by adding their values. So, 612 + 324 + 781 + 219 = 1936. - Therefore, the simplified expressions are:

$$ \begin{aligned} 2a + 612 + 7a + 324 &= 9a + 936 \\ 12y + 29y + 781 + 219 &= 41y + 1000 \end{aligned} $$
