How could you solve for x in the problem 3x+7=-x-1

lukranit [14]

Hello there!

$3x+7=-x-1\\$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 7 from both sides of the equation.

$3x+7-7=-x-1-7$

Simplify

$3x=-x-8$

Then you add by x from both sides of the equation.

$3x+x=-x-8+x$

Simplify

$4x=-8$

Divide by 4 from both sides of the equation.

$\frac{4x}{4}=\frac{-8}{4}$

Simplify it should be the correct answer.

$x=-2$

Answer⇒⇒⇒x=-2

Hope this helps!

Pls help math have no idea<br>multiply and simppify. <br>2x^2y^3z^2 • 4xy^4x^2

padilas [110]

Answer:

The answer is $8x^3y^7z^4$

Step-by-step explanation:

Given expression $(2x^2y^3z^2)(4xy^4z^2)$

we have to simplify the given expression.

$(2x^2y^3z^2)(4xy^4z^2)$

Combining like terms, we get

⇒ $8(x^2.x)(y^3.y^4)(z^2.z^2)$

As, $x^a.x^b=x^{a+b}$

⇒ $8x^3y^7z^4$
