Question
What is the value of x in the equation -2/3x + 9 =4/3x - 3?
Answer:
x = 6
Step-by-step explanation:
-2/3x + 9 =4/3x - 3
-2/3x = 4/3x - 3 - 9
-2/3x - 4/3x = -12
-6/3x = -12
-2x = -12
x = 12 : 2
x = 6
The desired value will be the solution to the equation ...
... (5 - a) = 20 + (6a - 1)
... 5 - a = 19 + 6a . . . collect terms
... 5 = 19 + 7a . . . . . . add a
... -14 = 7a . . . . . . . . . subtract 19
... -2 = a . . . . . . . . . . . divide by the coefficient of x
The value of the variable is -2.
2 pieces :)
Not sure if you wanted work but here is my explanation:
there are six pieces that she cut out, and she ate 1/3 of the six pieces,
1/3=2/6
since there are 6 pieces 1/3 would then equal 2 pieces. :)
Hope this helps:)
Given the equation, V = XLJ:
In order to solve for X, divide both sides of the equation by LJ:
V / (LJ) = (XLJ) / LJ
Doing so gives you the final answer:
V / LJ = X
Answer:
Step-by-step explanation:
M = 2J
M = H + 7
M + J + H = 53
Then combine first two equations and solve in terms of J:
2J = H + 7 --> H = 2J - 7
Substitute for H & M in last equation:
2J + J + 2J - 7 = 53
5J - 7 = 53
5J = 60
J = 12
Then plug J into other equations:
M = 24
J =12
H = 17
