-4(6x+3)= -12(x+ 10)
Lilit [14]

Answer:

9

Step-by-step explanation:

-4(6x+3)= -12(x+10)

<u><em>Let's do the first part:</em></u>

-4(6x+3)

<em>**distribute**</em>

-4 x 6x = -24x; -4 x 3 = -12 ->>> -24x - 12

<u><em>Let's do the second part:</em></u>

-12(x+10)

<em>**distribute**</em>

-12 x x = -12x; -12 x 10 = -120 ->>> -12x -120

-24x -12 = -12x - 120

<em>**Move variable to the left-hand side and change its sign**</em>

-24x +12x -12 = -120

-12x - 12 = -120

-12x = 108

x = 108/-12

x=9

SCORPION-xisa [38]
Make a system of equations and solve for each variable.

3m+8v=53
5m+2v=26

m= movie cost
v= game cost

multiply the bottom equation by 4(combination method)

3m+8v=53
20m+8v=104. Subtract

-17m = -51
m= 3

Plug back into one of the equations

5(3)+2v=26
15+2v=26
2v=11
v=5.5

m=$3
v=$5.5
