2x-12
x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6
5x + x - 6x + 2x = 2x
X=1.42857142857143
y = 2x + 5x - 12 = 7x - 12 So the zero is 12/7 = 1.7143 (approx)
2x-12
(3x + 2x) -12 =5x-12 the answer is 5x-12 it is just a simple case of simplifying
What is the answer to 2x - 5x plus 6.3 equals -14.4?
x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6
5x + x - 6x + 2x = 2x
X=1.42857142857143
y = 2x + 5x - 12 = 7x - 12 So the zero is 12/7 = 1.7143 (approx)
3(x + 2) = 5x - 12 3x + 6 = 5x - 12 6 = 2x - 12 6 + 12 = 2x x = 9
8x-7 plus 2x equals 6 plus 5x plus 2?
2x+3x = 5x
