Simplifying
2x + -1y + -3z = 5
Solving
2x + -1y + -3z = 5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
2x + -1y + y + -3z = 5 + y
Combine like terms: -1y + y = 0
2x + 0 + -3z = 5 + y
2x + -3z = 5 + y
Add '3z' to each side of the equation.
2x + -3z + 3z = 5 + y + 3z
Combine like terms: -3z + 3z = 0
2x + 0 = 5 + y + 3z
2x = 5 + y + 3z
Divide each side by '2'.
x = 2.5 + 0.5y + 1.5z
Simplifying
x = 2.5 + 0.5y + 1.5z
Answer:
216.66
Step-by-step explanation:
If the diameter is 26 feet, then the area is half of 26, which is 13.
then you find the square root of the radius which is 169.
Then you multiply 169 by pi, which is described as 3.14.
And you get 216.66, so therefore, the answer is 216.66.

Answer:
Answer is in attached picture
Step-by-step explanation:
There are no real solutions for the value of 'x'. The two solutions are complex. The fully simplifed answers would be:
x = 4 + 5i*sqrt(7)
x = 4 - 5i*sqrt(7)
Answer:
see explanation
Step-by-step explanation:
Given
2x² + x - 1 = 2 ( subtract 2 from both sides )
2x² + x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 3 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x + 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -
