Given:
The equations are:
To find:
The equation that show the relationship between a and c.
Solution:
We have,
...(i)
...(ii)
Equation (i) can be rewritten as:
...(iii)
From (ii) and (iii), we get
Therefore, the required equation is .
9e + 4 = 14 + 8e
9e = 10 + 8e (Subtract 4 from both sides)
e = 10 (Subtract 8e from both sides)
A
a) y+6x=5 if x= -1 then y+6(-1)=5 then y = 11
b) same thing if x = 3 then y+6(3)=5 y+18=5 subtract both sides by -18 and leave y on left then add 5+(-18)= 13 then y=13
B same as above
question (a) asks you to solve for y because x is -2
(b) asks you to solve for x because y is known
3x+2y=-6 if y = 3 you write 3x+2(3)=-6 3x+6=-6 move the +6 over to right side by subtracting 6 from both side 3x=-6 + -6 so 3x=-12 to get rid of the 3 and only leave the x you want to divide both side by 3 then x= -12/3 then the answer would be x=-4
Answer:
One less than 25, 24, times five is 120, and that is 4 times as much as 30 so you already know it is wrong.
