Solve the equation. Isolate the variable, x.
Note the equal sign, what you do to one side, you do to the other.
First, subtract 8 and 10x from both sides:
2x (-10x) + 8 (-8) = 12 (-8) + 10x (-10x)
2x - 10x = 12 - 8
Simplify. Combine like terms:
(2x - 10x) = (12 - 8)
-8x = 4
Isolate the variable, x. Divide -8 from both sides:
(-8x)/-8 = (4)/-8
x = -(4/8)
Simplify:
x = -1/2
-1/2 is your answer for x.

Answer:

Step-by-step explanation:
Consider similar triangles BMC and KMN.
In these triangles,

where O is the point of intersection of BC and MP.
Note that segment OP has the length the same as the side of the square ABCD. Hence,

Answer:
6x³ - 8x + 9
Step-by-step explanation:
Step 1: Write out expression
2x + 7 + 6x³ - 1 + 3 - 6x - 4x
Step 2: Combine like terms (x)
6x³ - 8x + 7 - 1 + 3
Step 3: Combine like terms (constants)
6x³ - 8x + 9
42+35 is 77
7(6+5) is 77 so yes

All the numbers in the first equation have a common factor of 2. Removing that gives
.. x +4y = 6
making it easy to solve for x
.. x = 6 -4y
My choice would be to solve for x using the first equation.

On second thought, it might actually be easier to solve either equation for 8y. That term then directly substitutes into the other equation (equivalent to adding the two equations).
.. 8y = 3x -11 . . . . . from the second equation
.. 2x +(3x -11) = 12 . . . substituting into the first equation
.. 5x = 23 . . . . . . . . . . collect terms, add 11 (what you would get by adding the equations in the first place)
.. x = 4.6
.. y = (3*4.6 -11)/8 = 0.35
