Question

solve the equation 3(x+1)=12+4(x-1) with explanation ​

Answer 1

Answer:

x = -5

Step-by-step explanation:

Simply open the bracket:-

$3(x + 1) = 12 + 4(x - 1) \\ \\ 3x + 3 = 12 + 4x - 4 \\ \\ 3x + 3 = 8 + 4x \\ \\ 3 - 8 = 4x - 3x \\ \\ - 5 = x$

Hope it helps.

Answer 2

Answer:

3x+3 = 12+4x-4

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

7-12 = x

therefore. x= -5
