Answer:

x = 3 is the solution

Step-by-step explanation:

3x + 4 = 5x - 2

when x = 3

so plug 3 into the equation where x is

so the equation becomes:

3(3) + 4 = 5(3) - 2

Then do the multiplication on both sides

9 + 4 = 15 - 2

Then do the addition and subtracition on both sides

13 = 13

Answer:

3x +4= 5x-2

3(3) +4 = 5(3) -2 (plug in the x values)

9+4= 15-2 (do the multiplication on both sides)  

13= 13 (do the addition/ subtraction. pretty much all you're doing, is making sure that with the given x-value, the equation is true. and it is :))
