3x - 8y equals -18 2x plus 5y equals 19?
(2, 3)
Y equals 5x plus 18 y equals 2x plus 9?
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
What is the answer for x2 plus 3x-18 equals 0?
X2 + 3X - 18 = 0What two factors of - 18 add up to 3 ??(X - 3)(X + 6)============so, by the zero sum rule,X = 3X = - 6
What is 3x plus 7y if x equals 6 y equals 4?
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
What is the solution to 3x-3 equals -3x plus -3?
x = 0
3x - 8y equals -18 2x plus 5y equals 19?
(2, 3)
3x plus 9 equals 27?
27-9 =18. 18/3 =6
X2 plus 3x - 18 equals 0?
x^2+3x-18=0 (x+6)(x-3)=0
Solve 3x plus 7 equals 25?
25-7=18 18/3=6
Y equals 5x plus 18 y equals 2x plus 9?
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
What is the answer for x2 plus 3x-18 equals 0?
X2 + 3X - 18 = 0What two factors of - 18 add up to 3 ??(X - 3)(X + 6)============so, by the zero sum rule,X = 3X = - 6
What is 3x plus 7y if x equals 6 y equals 4?
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
What is the solution to 3x-3 equals -3x plus -3?
x = 0
One of the roots of the equation x2 plus 3x - 18 equals 0 is 3 what is the other root?
x2 + 3x - 18 = 0 (x - 3)(x + 6) = 0 x = 3 or -6
What is the answer to 3x plus 7 equals 3?
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
3x plus 2y equals 18?
one solution to that is 3*6 + 2*0=18 but, if you need both numbers then 3*2 + 2*3
How do you solve x2 plus 3x plus 3 0?
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
