2/3(3x+9)=-2(2x+6)<br><br><br> Solve for x

NikAS [45]

Greetings!

Solve for <span>x.
</span> $2/3(3x+9)=-2(2x+6)$
Distribute the Parenthesis.
$2/3*3/1x+2/3*9/1=-2*2x-2*6$
Simplify.
$6/3x+18/3=-4x-12$
Reduce.
$2x+6=-4x-12$
Add 12 to both sides.
$(2x+6)+12=(-4x-12)+12$
Simplify.
$2x+18=-4x$
Subtract both sides by 2x.
$(2x+18)-2x=(-4x)-2x$
Simplify.
$18=-6x$
Divide both sides by -6.
$(18)/-6=(-6x)/-6$
Simplify.
$-3=x$
$x=-3$

Hope this helps.

Answer:

A. -(5y+2) + y = 5

Step-by-step explanation:

Solving the above Equation given to us in the Question,

-x + y = 5...... Equation 1

x - 5y = 2....... Equation 2

Step 1

We make x subject of the formula in Equation 2

---> x= 5y + 2

Step 2

This would be to substitute 5y + 2 for x in Equation 1

-x + y = 5...... Equation 1

-(5y+2) + y = 5

Hence, Option A is the correct option

Help please :(..............

You want to isolate b, so start by multiplying the whole equation by three to get rid of it in the denominator:

(v=1/3 bh)3

3v=bh

Then to isolate b divide the whole equation by h:

(3v=bh)/h

3v/h=b
