Question

What do you get from adding -9x+4y=1+9x-8y=-29 needing help

Answer 1

To solve this question, we have to identify the like terms, recall that two terms are called like terms if they have the same variable with the same exponent.

In this case, the like terms are:

9x and -9x, 4y and -8y and 1 and -29.

Adding like terms we get:

`\begin{gathered} (9x-9x)+(4y-8y)=1-29, \\ 0x-4y=-28. \end{gathered}`

Answer:

`-4y=-28.`
