2x plus 6 equals -6 5x plus 7y equals 1?
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
5y plus 8 equals 7y-6?
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
What is 7y-6 equals 5y-14?
7y - 6 = 5y - 147y - 5y = 6 - 142y = -8y = -8 ÷ 2y = -4
What slope o the parallel line of -5x-7y-6?
Slope is found by this form. Y = mX + c ( m = slope ) - 5X - 7Y - 6 = 0 ( I assume this is what you mean ) - 7Y - 6 = 5X - 7Y = 5X + 6 Y = - 5/7X - 6/7 The slope would be in this instance, - 5/7 ----------
What is the answer to 7y-6 equals 8?
OK:7y-6=87y+6-6=8+67y = 14y = 2.Y is equal to 2. Hope this helps!

If x equals 9 and y equals 6 what is 10x plus 7y?
Substitute the values of x and y in 10x + 7y, thus: 10x + 7y = 10*9 + 7*6 = 90 + 42 = 132
How do you find a reciprocal of 7y?
So Hey, Step 1: 7y=7y :) Step 2: 7y/7y=49^8 :) Step 3: 49^8/ = *6r1 :) So Hey Again so like you saw all the steps right?? Ok, GOOD :)............................................................................................................................................................................................................. So the reciprocal of 7y is 6^1 :)
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 LCM of 7y2 x 49y8?
Since 98y9 is a multiple of 14y2, it is automatically the LCM of this problem.
7(y-6)=28?
7y-42=28 ==> 7y=42+28 => y=70/7. => 10
What is 7y 42 factored out?
7(y + 6)
