For this case we must add the following expressions:
[tex](5y + 4) + (- 2y + 6) =[/tex]
We eliminate the parentheses, we take into account that applying the distributive property of the sign on the terms within the second parenthesis that:
[tex]+ * - = -\\+ * + = +\\5y + 4-2y + 6 =[/tex]
We add similar terms:
[tex]5y-2y + 4 + 6\\3y + 10[/tex]
ANswer:
[tex]3y + 10[/tex]
