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

$x=-5$
