Question

Solve the equation for x.

120(2x − 2) = 240
A) 2
B) 8
C) 12
D) 16

Answer 1

the answer is A because 2time 2 is 4-2 =2 and then 120times 2 =240

Answer 2

x=2

Explanation:

First,

120(2x - 2)=240

multiply 120, by 2x

(240x)

we cant forget the second one, so again, multiply 120, by -2

you get - 240

so now, 240x-240=240

add 240 to the other side

-240+240=0

other side

240+240=480

so, 240x=480

divide by 240 on each side

x=2

Hope this helps, have a nice day!
