Answer:
x=-11
Step-by-step explanation:
3(1-3x)=2(-4x+7)
1) Distribute 3 to 1 and -3x:
3-9x=2(-4x+7)
2) Distribute 2 to -4x and 7:
3-9x=-8x+14
3) Subtract 3 from both sides::
-9x=-8x+11
4) Add 8x to both sides:
-1x=11
5) Divide both sides by -1:
x=-11
Footnotes:
-The <u>Distributive</u> property says a(b+c)=ab+ac
-When you have a negative variable, there is an implied (-1) before the variable :)
Given:
a varies jointly as b and c.
a=6 when b=2 and a=3.
To find:
The variation constant and the equation of variation.
Solution:
a varies jointly as b and c.
...(i)
Where, k is the constant of proportionality.
a=6 when b=2 and a=3.
The value of k is 1.
Putting k=1 in (i), we get
Therefore, the variation constant is 1 and the equation of variation is .
