X + 7/6 = 2x - 7/6
x + 7/6 (-7/6) = 2x - 7/6 - (7/6)
x = 2x - 14/6
x (-2x) = 2x (-2x) - 14/6
-x = -14/6
x = 14/6 or 2.33
x = 2.33
hope this helps
Answer:
W=7 and L=11
Step-by-step explanation:
We have two unknowns so we must create two equations.
First the problem states that length of a rectangle is 10 yd less than three times the width so: L= 3w-10
Next we are given the area so: L X W = 77
Then solve for the variable algebraically. It is just a system of equations.
3W^2 - 10W - 77 = 0
(3W + 11)(W - 7) = 0
W = -11/3 and/or W=7
Discard the negative solution as the width of the rectangle cannot be less then 0.
So W=7
Plug that into the first equation.
3(7)-10= 11 so L=11
Answer:

Step-by-step explanation:
Answer:
7
Step-by-step explanation:
add 7 to 3x
Then: 4x-3x=1x which gives:
1x=7
7/1=7
