Oh, dude, 3x equals 42? That's like saying you have three times some mystery number, and that mystery number equals 42. So, if you divide 42 by 3, you'll find out what that mystery number is. It's like basic math, man.
Well, isn't that a happy little math problem we have here! To find the value of x, we simply need to divide both sides of the equation by 3. So, x equals 14. Just like painting a beautiful landscape, sometimes all it takes is a little brushstroke of division to reveal the hidden beauty within the numbers.
3x + 12 = 42 3x = 30 x = 10
If: 3x = 15 Then: x = 5
2x+3x = 5x
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
3x+7=37 -7 -7 3x=30 /3 /3 x=10
