-6x-4(-7x-13)=-58 <br> What the answer

taurus [48]

-6x-4(-7x-13)=-58

Multiply the bracket by -4

-6x-4(-7)-4(-13)= -58

-6x+28x+52= -58

22x+52= -58

Move +52 to the other side. Sign changes from +52 to -52.

22x+52-52= -58-52

22x= -110

Divide by 22.

22/22x= -110/22

x= -5

Answer: x= -5

Even would be helpful if you just gave me the equation to solve it and I can do the rest. mart had a sale for labor day on DVD's

erastova [34]

x - price of a video tape

y - price of a DVD

$\left\{\begin{array}{ccc}2x+3y=134\\x+5y=179&|\text{subtract 5y from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}2x+3y=134\\x=179-5y&|\text{substitute to the first equation}\end{array}\right\\\\2(179-5y)+3y=134\qquad\text{use distributive property}\\\\(2)(179)+(2)(-5y)+3y=134\\\\358-10y+3y=134\qquad\text{subtract 358 from both sides}\\\\-7y=-224\qquad\text{divide both sides by (-7)}\\\\\boxed{y=32}\\\\\text{Put the value of y to the second equation}\\\\x=179-5(32)\\\\x=179-160\\\\\boxed{x=19}$

<h3>Answer: video tape cost $19 and DVD cost $32.</h3>
