Answer:

x = 2

Step-by-step explanation:

Given the expression 5x−4 = 3x +8, we are to solve for the value of x;

Step 1: Collect the like terms so that the variables are on one side and Constants on the other side

5x - 3x = 8-(-4)

5x - 3x = 8+4

Step 2: Evaluate the expression in both sides

5x-3x = 8+4

2x = 12

Step 3: Divide both sides by 2

2x = 12

2x/2 = 12/2

x = 6

Hence the value of x is 2
