if:
2x + 6 = -6
then:
2x = -12
x = -6
if:
5x + 7y = 1
then:
5(-6) + 7y = 1
7y = 31

2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
What is 2x plus 4y-5x plus 3y?
2x + 4y - 5x + 3y = 7y - 3x
How do you rewrite this equation so that y is a function of x 1 plus 7y equals 5x-2?
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
-4x plus 7y equals 9 2y equals -5x - 22?
(-4, -1)
What is the answer to simplify 5x-6y-2x-y?
The simplified expression is 3x - 7y.
-2x-4y plus 5x-7y equals?
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
What is 2x plus 4y-5x plus 3y?
2x + 4y - 5x + 3y = 7y - 3x
How simplify 5x plus 3y-2x plus 4y?
3x + 7y
How do you rewrite this equation so that y is a function of x 1 plus 7y equals 5x-2?
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
-4x plus 7y equals 9 2y equals -5x - 22?
(-4, -1)
What is the sum of -5x plus 7y-6z?
-5x+7y-6z
Simplify 4x plus 7y plus 2x-3y equals?
6x plus 4y
Are the graphs of 2x plus 7y equals 6 and 7y equals 2x plus 6 parallel?
Yes, they are. If you solve 2x + 7y = 6 for y, you get y = (-2x + 6) / 7. If you solve 7y + 2x + 6 = 0 for y, you get y = (-2x - 6) / 7. As you can see, both equations have the same slope. Therefore they are parallel. You can punch those equations into a graphing calculator and visually verify that they are indeed parallel.
What is the slope of 2x-7y equals 14?
2x-7y=14 2x-14=7y from this equation the slope is 2/7
What is the answer to simplify 5x-6y-2x-y?
The simplified expression is 3x - 7y.
