Find the value of x
I would like all 3 answers and how to get them (show work).
Thanks!

Answer:
4) 4
5) 6.5
6) 14
Step-by-step explanation:
Question 4 equation: [tex](\frac{12*5}{2} * 2) + (\frac{5x}{2} *2) = 80[/tex] ⇒ [tex]60 + 5x = 80[/tex] ⇒ [tex]5x = 20[/tex] ⇒ [tex]x=4[/tex].
Question 5 equation: [tex]16x=104[/tex] ⇒ [tex]x=6.5[/tex].
Question 6 equation: [tex]\frac{10x}{2} = 70[/tex] ⇒ [tex]5x=70[/tex] ⇒ [tex]x=14[/tex].
