4(x + 4y) + 3(4x + y)

1 answer:

5 0

The simplified version of this would be: (4x+16y)+(12x+3y). You then combine like terms (4x+12x=16x) and (16y+3y=19y). Since this is the most simplified you can make the equation THE ANSWER would be 16x+19y

*NEED HELP!*

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,

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