Question 52985
5(x – 1) 
This implies that every term with the brackets(in this case x and -1) should be multiplied with every term immediately outside the bracket(in this case 5)

So you get 5x -5
5x -5 = 3x + 8 

Subtracting 3x on both sides
2x-5 = 8

Adding 5 on both sides
2x = 13

Dividing by 2 on both sides
X = 13/2

This is you answer :-)
