Hey!

------------------------------------------------

Steps To Solve:

9b = -6 + 10b

~Subtract 10b to both sides

9b - 10b = -6 + 10b - 10b

~Simplify

-1b = -6

~Divide -1 to both sides

-1b/-1 = -6/-1

~Simplify

b = 6

------------------------------------------------

Hence, the answer is $\Large\boxed{\mathsf{b~=~6}}$

*NEED HELP!*

Vlad1618 [11]

Answer and Step-by-step explanation:

$Hello!~$

$Let's~answer~your~question!$

$So,~for~this~equation,~we~need~to~use$ $~the~distributive~property~of$ $~multiplication.~but,before~we~start~to~solve$ $this~equation,~let's~get~to~know~what$

$distributive ~property ~of~multiplication~means!$

Distributive property of multiplication :

$Distributive~property~of~multiplication~states~that$ $when~a~~number~is~multiplied$

$by~the ~sum ~of~ two~ numbers,$ $the~ first~ number ~can~ be ~distributed ~to$ $both ~of~those$ $numbers~and~multiplied~by~each~of~them$ $separately.$

→ $a*(b+c)=a*b*+~a*c$

Now, that we know what it means let's apply it in our equation:

 $(2*x)+(2*7)=36$ 

Now, we simplify:

 $2x+14=36$ 

Divide both sides by 2 in the equation:

 $\frac{2x+14}{2} =\frac{36}{2}$ 

Simplify :

 $x+7=18$ 

Thus, the first correct step is option B,

 $then~comes,~option~"A"~then,~option~"F"~as~shown~above$ $The~remaining~options~are~not~enough~information~to~solve~the~given$ $equation:(x + 7) = 36.$
