Assume the equation is 2x + 9y = 18.
Then, there is no answer to this problem without the further details about the values for x or y!
Include some information and objective for the problem. Some details you might want to include are:
- Find the slope of the equation. [Then, you need to solve for y and use the slope-intercept form y = mx + b!]
- Find the solution, given another equation.
- Graph the function.

What is 2x plus 9y - 6x?
9y - 4x
How many values of x and y satisfy the equations 2x plus 6y equals 12 and 3x plus 9y equals 18?
2X + 6Y = 12 3X + 9Y = 18 try elimination - 3(2X + 6Y = 12) 2(3X + 9Y = 18) - 6X - 18Y = - 36 6X + 18Y = 36 ================= I will say this system is dependent and an infinite number of solutions can be found.
What is 2x plus 3y plus 4x plus 9y?
2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)
What is 6x plus 3y plus 6y-2x?
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
What does 12y plus 3 equals 9y-15 equal?
12y+3=9y-15 3y=-18 y=-6
What is 2x times x times y divided by 9 times y squared?
18
What is 2x plus 9y - 6x?
9y - 4x
How many values of x and y satisfy the equations 2x plus 6y equals 12 and 3x plus 9y equals 18?
2X + 6Y = 12 3X + 9Y = 18 try elimination - 3(2X + 6Y = 12) 2(3X + 9Y = 18) - 6X - 18Y = - 36 6X + 18Y = 36 ================= I will say this system is dependent and an infinite number of solutions can be found.
What is 2x plus 3y plus 4x plus 9y?
2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)
-2x plus 9y equals -35?
-2x+9y=-35 add 2x to both sides to get 9y=2x-35 divide both sides by 9 to get y=2/9 x - 35/9 the Y intercept is 0, ~-3.889 and the slope is 2/9
What is the factor of 18xy-45yz using the GCF?
63
Finding the slope and y- intercept of a line 9y plus 2x plus 3 equals 13 plus 2x?
9y + 2x + 3 = 13 + 2xSubtract 2x from each side:9y + 3 = 13Subtract 3 from each side:9y = 10Divide each side by 9:y = 10/9The graph is a straight horizontal line. The slope is zero. The y-intercept is [ y = 10/9 ).
What is -9y equals -18?
9
What is 6x plus 3y plus 6y-2x?
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
What is 9y-11 equals 7?
9y-11=7 +11 +11 9y=18 y=2
Simplify 3x - 2y plus 9 plus 9y - x?
3x-2y+9+9y-x = 2x+7y+9
What two numbers have a difference of 9 and a sum of 18?
1. x - y = 92. x + y = 18Adding 1. & 2. gives:3. 2x = 27x = 27/2x = 13.5Substituting x = 13.5 into 1. gives:13.5 - y = 9y = 13.5 - 9y = 4.5The two numbers are therefore 13.5 & 4.5.
