Oh, dude, like, a numeral coefficient is a number that multiplies a variable, you know, like 5x or 7y. On the other hand, a literal coefficient is a coefficient that contains a letter or a variable, like 3a or 4b. So, one's just a number, and the other's a number with a side of alphabet soup.
16+7y-8 = 7y+16-8 = 7y+8
a + 7y

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
6x2 - 4x (6/2)x2 - (4/2)x = 3x2 - 2x ========
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.
-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'.
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

7y-42=28 ==> 7y=42+28 => y=70/7. => 10
39 - 7y = 18,-7y = 18 - 39-7y = -21-7y/-7 = -21/-7y = 3
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
16+7y-8 = 7y+16-8 = 7y+8
a + 7y

It is simply: 7y+46 or 7y-46
