Mx = Nx - Pt
To isolate 'x', we have to group all terms that have 'x' together
We have Mx on the left-hand side of the equation and Nx on the right.
Moving Nx to the left-hand side of the equation, we have:
Mx - Nx = Pt
From here we factorize 'x'
x (M - N) = Pt
Then we divide both sides by (M-N)
Answer:
5
Step-by-step explanation:
3x=2x+5
3x-2x=5
x=5
Answer: x=5
Answer:
-3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
4x + 2x - 5 - 6 = 12x + 7
6x - 11 = 12x + 7
<em>collect like terms</em>
6x - 12x = 7 + 11
-6x = 18
-x = 3
x = -3
The sum of the inside angles of a 5 sided figure needs to equal 540 degrees.
Add all the angles together to equal 540 and solve for x. Once you have the value for x you can use that to figure out all the angles.
X-8 + 3x-11 + x + 8 + 2x + 7 + x = 540
Simplify by combing like terms:
8x - 4 = 540
Add 4 to both sides:
8x = 544
Divide both sides by 8:
X = 68
Now replace x with 68 in each angle and solve:
U = 68-8 = 60
V = 3(68)-11 = 204-11 = 193
W = 68 + 8 = 76
Y = 68
Z = 2(68) + 7 = 136 + 7 = 143
Set up the synthetic division using the coefficients of the numerator and the root in the denominator. Divide using the rules for synthetic division.
x^3 + 1 - 7 / x -2
