Oh, dude, this is like a math riddle! So, if 3x equals 12, then x must equal 4, right? And if y equals 3 times x, which we now know is 4, then y must equal 12. So, y equals 12, but like, you probably already knew that, huh?
Well, if 3x equals 12, then x must equal 4. And if y equals 3x, then y must equal 3 times 4, which is 12. So, in conclusion, y equals 12. Math can be a real brain teaser, huh?
If 3x equals 12, that means x equals 4 (since 3 multiplied by 4 equals 12). If y equals 3x, and x is 4, then y equals 3 multiplied by 4, which equals 12. Therefore, y equals 12.
3x - y = 12 is the same as 3x - 12 = y, or y = 3x - 12.
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
y = -1x/2 3x + 6y = 0 -3x -3x __________ 6y = 0 - 3x --- -------- 6 6 y= -3x/6 y= -1x/2
If you mean: y = 3x+1 then the value of y will equal 10
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)
