What else can I help you with?
What is X - Y equals 6 and -3y equals X plus 22?
x-y = 6 -x-3y = 22 -4y = 28 y = -7 So by substituting: x = -1 and y = -7
What is the y intercept of the line y equals 8x plus 7?
7 is the y intercept
What is the value of x and y in x plus y equals -7 x-y equals 1?
-6
How do you solve y equals 7 plus x?
y=7+x =x=7-x
What is -7 y equals -42?
35
What is y-5 over 4 equals 7?
(y-5)/4 = 7 y-5 = 28 y = 33
Find an equation of variation where y varies directly as x and y equals 28 when x equals 7?
4x= y
Y squared plus y squared - 56 equals?
y2 + y2 - 56 let's factor it such as = 2y2 - 56 = 2(y2 - 28) = 2[y2 - (√28)2] = 2(y - √28)(y + √28) = 2(y - √4*7)(y + √4*7) = 2(y - 2√7)(y + 2√7)
What does y equals -18 equals 9y - 5y plus 10?
4y + 10 = -18 4y = -28 y = -7
What is 28 - 4y?
if your solving for y, it's y=7. you have to get y alone and to do that you have to divide 4y by 4. now you have y alone. you also have to divinde the other side of the equation(28) by 4...which equals 7
What is X - Y equals 6 and -3y equals X plus 22?
x-y = 6 -x-3y = 22 -4y = 28 y = -7 So by substituting: x = -1 and y = -7
What is the graph of -4x plus 7y equals -28?
-4x=7y-28 -4x+28=7y -4x/7+4=y A line with a y-int of 4 and a slope of -4/7
X-3y equals 7 -3x plus 16y equals 28?
-3x+16y = 28 3(x-3y = 7) Multiply the bottom equation by 3 then add both equations together in order to eliminate x: 7y = 49 y = 7 Substitute the value of y into the original to find the value of x: So: x = 28 and y = 7
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 line 14y-2x equals 28?
14y - 2x = 28 14y = 2x + 28 y = x/7 + 2 Therefore, the slope is 1/7.
What property of equality would you use to solve y divided by 7 equals 28?
Multiply both sides by 7.
If 2y plus 26 equals 28 what does y equals?
2y+26 = 28 2y = 28-26 2y = 2 y = 1
