Answer:
x=3
Explanation:
You can start of by adding 4x and 2x because they both share the same variable "x". Now you have 6x-3=15. Using the addition property of equality, you can add 3 on both sides of the equation to cancel it out. You are left with 6x=18. Divide both sides by 6 and that leaves you with x=3
x = 3
4x + 2x - 3 = 15 ← collect like terms on left side
6x - 3 = 15 ( add 3 to both sides )
6x = 18 ( divide both sides by 6 )
