-9y-15x ---- -3
15xplus 3
The GCF is 3.
You can take 3 out of both of those.
15x - 15y = -10 :add 15y to both sides ---> 15x = 15y - 10add 10 to both sides ---> 15x + 10 = 15ydivide both sides by 15 ---> x + 10/15 = y ---> x + 2/3 = yThe final equation y = x + 2/3 in the form y = mx + b, with m =1 and b = 2/3.Slope (m) is 1, and y-intercept (b) is 2/3.
-9y-15x ---- -3
The GCF is 15x.
steps: 3(5x-7) =(3)(5x-7) =(3)(5x)+(3)(-7) answer: 15x-21

15x-20y= 7 5y-3 +10x
OK, SO 15x-3 = 2x+1 15x - 3 + 3 = 2x + 1 + 3 (add three to each side) 15x=2x+4 (simplIfy) 15x-2x=2x-2x+4 (subtract 2x from each side) 13x=4 (simplify) (13x/13)=(4/13) (divide each side by 13) x≈0.30769231
-15x - 3
39x - 45 = 15x - 24
15xplus 3
The product of 15 and x is 15x. If you then want to substitute a numerical value for x to evaluate the expression of 15x when x equals that number then just multiply. For example, if x = 3, then 15x = 15(3) = 45 if x = 10, then 15x = 15(10) = 150 Good luck! :-)
