Solve for y 2x+y-3z=5

Elza [17]

Answer:

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

<u>To solve:</u>

The value of y.

$\Longrightarrow: \sf{\sqrt{2x+y-3z}=5}$

<u>First, you have to subtract by 2x-3z from both sides.</u>

$\Longrightarrow: \sf{2x+y-3z-\left(2x-3z\right)=25-\left(2x-3z\right)}}$

<u>Solve.</u>

$\Longrightarrow: \boxed{\sf{y=25-2x+3z}}}$

<u>Therefore, the correct answer is "A. y=-2x+3z+25".</u>

I hope this helps, let me know if you have any questions.

Name a number that has the same absolute value as 23

IRINA_888 [86]

Answer: A number with the same absolute value of 23 is -23.

Explanation: The absolute value of a number is how far it is from zero, and the absolute value of a number is always positive, unless the number is 0, in which case the absolute value is neutral, and the absolute value is 0.

Examples: 6 is 6 away from zero, so the absolute value of 6 is 6.

−6 is 6 away from zero, so the absolute value of −6 is 6.
