3(2x + 4) - 4(x - 1) = -8​

Answer 1

Step-by-step explanation:

6x+12-4x+4= -8

2x= -24

so X= -12

Answer 2

Answer:

☆ Given:

$3(2x+4)-4(x-1)=-8$

☆ To find:

Value of x

☆ Concept:

Use the cross multiplication formula to find the first part then find the value of x

☆ Solution:

>> 3(2x+4)-4(x-1)=-8

>> 6x+12‐4x+4=-8

>> 6x-4x+12+4=-8

>> 2x+16=-8

>> 2x=-8-16

>> 2x=-24

>> x=-24/2

>> x=-12

☆ Answer:

So , the value of x is -12
