14x plus 7y equals -7?
-8x-6y=-18
What is the answer for the ordered pair form x plus 7y equals 39 3x minus 2y equals 2 using substitution?
If you mean: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
Solve this equation using subtitution x plus 7y equals 39 and 3x-2y equals 2?
x + 7y = 39 So x = 39 - 7y Substitute for x in the second equation: 3(39 - 7y) - 2y = 2 117 - 21y - 2y = 2 115 = 23y y = 5 Substitute this value for y back into the first equation: x + 7*5 = 39 x + 35 = 39 x = 4
What equation could be used to solve y² plus 7y equals 18 by factoring?
y2+7y=18 y2+7y-18=0 (y+9)(y-2)=0 y=-9 & y=2
6x plus 7y equals 96 6x - 7y equals 12?

What is 39-7y equals 18 equal?
39 - 7y = 18,-7y = 18 - 39-7y = -21-7y/-7 = -21/-7y = 3
What is 18 equals 39-7y equal -with the work shown?
18=39-7y minus 18 from both sides (0=21-7y) subtract 21 from both sides to get the variable and the number on opposite sides -21=-7y -21/-7y= ____ y= ___

7y plus 3 equals y plus 18?
7y+3=y+18 Subtract three 7y=y+15 Subtract y 6y=15 Divide Y=15/6 That's your fraction if you need a decimal just type it in the calculator...
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 slope of 14x plus 7y equals -9?
14x+7y=-9
Solve this equation using subtitution x plus 7y equals 39 and 3x subtract 2y equals 2?
From first equation: x = 39 - 7ySubstitute this in second equation: 3(39 - 7y) - 2y = 2ie 117 - 21y - 2y = 2ie 115 = 23yie y = 5, making x = 4.
