Solve 3[-x + (2 x +1)]=x-1

Gala2k [10]

Question :

Solve 3 [-x + (2x + 1) ] = x - 1

Solution :

⇒ 3 [-x + 2x + 1] = x - 1

⇒ 3 [x + 1] = x - 1

⇒ 3 × [x + 1] = x - 1

⇒ 3x + 3 = x - 1

⇒ 3x - x + 3 = -1

⇒ 2x + 3 = -1

⇒ 2x = -1 - 3

⇒ 2x = -4

⇒ x = -4 / 2

⇒ x = -2

If x =2 y=3 z=4 solve the following x² + y²

Tanya [424]

Answer:

Step-by-step explanation:

Given x = 2, y = 3 and z = 4. We'll evaluate the value of x² + y² with given condition.

First, remind that we are only given the expression of x-term and y-term only and therefore, z-term is not included - it's not to be considered.

Substitute x = 2 and y = 3 in the expression:

$\displaystyle{2^2+3^2 = 4+9}\\\\\displaystyle{4+9 = 13}$

Hence, the value of x² + y² when x = 2 and y = 3 is 13.

Please let me know if you have any questions!

Answer:

$x = 18$

Step-by-step explanation:

Given

$DC=14$

$CE=x$

$DE=32$

Required

Find x

Because C is between D and E;

$DE = DC + CE$

Substitute values for each;

$32 = 14 + x$

Collect Like Terms

$x = 32 - 14$

$x = 18$
