Call the unknown value of (x - y) d. Then x = y + d; from the problem statement,
y + d + 2(y + d) +5 = y + 2y; expanding yields
y + d + 2y + 2d + 5 = y + 2y; (y + 2 y) can be subtracted from both sides and terms in d collected to result in 3d + 5 = 0; 3d = -5; d = -5/3.
it equals 13X.
x=1
What is the answer to 2x - 5x plus 6.3 equals -14.4?
-2x plus 3y equals 1
x = 0
X=7
NM equals 2x + 1, as stated in the question!
x=0
8x-7 plus 2x equals 6 plus 5x plus 2?
3x
2x+3x = 5x
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
