Solve the equation for x.4+2(x-4)=-7(x+7)​
OverLord2011 [107]

Answer:

x=-5

Explanation:

we have

4+2(x-4)=-7(x+7)

Solve for x

That means----> Isolate the variable x

Applying the distributive property both sides

4+2(x)+2(-4)=-7(x)-7(7)

Remember that

(+1)(-1)=-1

4+2x-8=-7x-49

Combine like terms left side

2x-4=-7x-49

Adds 7x both sides

2x-4+7x=-7x-49+7x

9x-4=-49

Adds 4 both sides

9x-4+4=-49+4

9x=-45

Divide by 9 both sides

x=-5
