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

group like terms:

4x+43=19

subtract 43 from both sides:

4x+43=19

-43 -43

simplify:

4x=-24

divided both sides by 4:

x=-6

Answer:

x = 1/2

Step-by-step explanation:

$- 3x + 1 + 10x = x + 4 \\ - 3x + 10x - x = 4 - 1 \\ ( - 3 + 10 - 1)x = 3 \\ 6x = 3 \\ x = \frac{3}{6} = \frac{1}{2} \\ x = \frac{1}{2}$
