VARVARA [1.3K]2 years ago
4 0

Answer:

x= -6 | I only have an answer for #7 but you should use a website called Symbolab :)

Step-by-step explanation:

x+16+x+12+2x+15=19

<em>group like terms: </em>

4x+43=19

<em>subtract 43 from both sides:</em>

4x+43=19

   -43 -43

<em>simplify</em>:

4x=-24

<em>divided both sides by 4:</em>

x=-6
