When you solve an equation, always make sure you check your work. One little mistake can throw the whole problem off.

7(2-4(-11))=322

7(2+44)=322

7(46)=322

322=322 (The problem does check out)

7(2 - 4x ) = 322

First solve the bracket and for that multiply 7 to both terms of bracket on LHS

14 - 28x = 322

place similar terms on same side

14 - 322 = 28x

solve the LHS

-308 = 28x

-11 = x

so, x = -11

7(2-4x)=322

[7*2 - 7*4x] = 322

14 - 28x = 322

14 - 14 -28x = 322 -14

-28x = 308

-28x / -28 = 308 / -28

x = -11

You need to multiply 7 into the brackets to get 14-28x=322. next subtract 14 fom both sides to get -28x=308 next take 308 and divide by-28. that will get the answer.

...7(2-4x) = 322

14 - 28x = 322

14-322 = 28x

28x = 14-322

28x = -308

(28x)/28 = (-308)/28

x=-11
