How do you solve the equation of 4-2y equals 7y plus 13?
Answer: y= -1 Solution: 4 - 2 y = 7 y + 13 subtract 7 y from both sides: 4 - 2 y - 7 y = 7 y + 13 - 7 y 4 - 9 y = 13 subtract 4 form both sides: 4 - 4 - 9 y = 13 - 4 - 9 y = 9 now divide both sides by - 9: -9 y / - 9 = 9 /-9 y = -1
What is y-5 over 4 equals 7?
(y-5)/4 = 7 y-5 = 28 y = 33
X-y equals 5 2x plus y equals 7 answer?
x - y = 5 + 2x + y = 7 => 3x + 0 = 12 => 3x = 12 => 3x/3 = 12/3 => x=4 x-y=5 2x+y=7 =>4-y=5 =>2(4)+y=7 =>y=4-5 =>8+y=7 =>y=-1 =>y=-1 So, the answer would be x=4 and y=-1
What is the slope and the y-intercept if y equals 3x-4?

What is the answer to 5k-y-k 7?
-2
What does y equal if 4y -7 equals 3y -4?
4t-7=3y-4 y=3
What is the answer to the systems of equations x minus y equals 10 x plus y equals 4?
X - Y = 10 X + Y = 4 -------------------+ ( add them ) 2X = 14 X = 7 ----------find Y in one of the equations; top looks good 7 - Y = 10 - Y = 3 Y = - 3 ---------------check both equations for consistency 7 - (- 3) = 10 7 + 3 = 10 10 = 10 ------------checks in top 7 + (- 3) = 4 7 - 3 = 4 4 = 4 ------------checks and is consistent (7, - 3) ( the answer )
What two numbers multiply to negative 7 and add to 4?
11
What are the slope and the y-intercept of this equation y -4x - 7?
If you mean: y = -4x-7 then the y intercept is -7 and the slope is -4
