The coefficient of 7y is 7 because 7 is the number found before the variable, y. This suggests that the given number is 7*y.
In any number ax, where a is a real number and x is a variable, a would be the coefficient and the product of that number would be a*x.

Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
What is -7y plus 4y?
-7y + 4y = -3y
What does Coefficient mean?
6x2 - 4x (6/2)x2 - (4/2)x = 3x2 - 2x ========
What is the slope of the line 6x-7y10?
if: 6x - 7y = 10 then -7y = 10 - 6x y = 6x/7 - 10/7 The slope is now the coefficient of x, which is 6/7.
What is the slope of -7y plus 21 equals 3x?
-7y + 21 = 3x Add '7y' to both sides 21 = 3x + 7y Subtract '3x' from both sides 21 - 3x = 7y 'Swop around'. 7y = -3x + 21 Divide both sides by '7' y = -(3/7)x + 3 The slope of a straight line is the coefficient of 'x' In this case it is ' -3/7'.
What is the slope of the line 14y-2x equals 28?
14y - 2x = 28 ie 7y - x = 14 ie 7y = x + 14 or y = (1/7)x + 14 The slope is the coefficient of x, or 1/7
What is 39-7y equals 18 equal?
39 - 7y = 18,-7y = 18 - 39-7y = -21-7y/-7 = -21/-7y = 3
7y-2 equals 14yplus 61?
y=-9 7y-2=14y+61 7y-2-7y=14y+61-7y -2=7y+61 -2-61=7y+61-61 -63=7y -63/7=7y/7 -9=y
What is 16 plus 7y - 8?
16+7y-8 = 7y+16-8 = 7y+8
What is a plus 7y?
a + 7y
