Question

3/7x+5=8 A.7 B.1 2/7 C.7 2/3 D.-7

Answer 1

Hey there!

Your answer =
`(x=7)`


`\left[\begin{array}{ccc}\boxed{ (3)/(7) *x+5-(8)=0 } \\ \\ (Simplify \ (3)/(7)) \\ \\ \boxed{(( (3)/(7)*x)+5)-8=0} \\ \\ (do \ the \ whole \ fraction \ using \\ (7) \ as \ the \ bottom \ denominator) \\ \\ \boxed{\boxed{5= (5)/(1) = (5*7)/(7)}} \\ \\ pull \ out \ like \ factors \\ \\ 3x - 21 = 3 * (x - 7) \\ \\ \boxed{ (3*(x-7))/(7)*=0*7} \\ \\ x-7 = 0 \\ \\ add \ seven \ to \ both \ sides \\ \\ (7) \ is \ the \ answer! \end{array}\right]`

I hope this helps you!
