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.

How do I solve the following system of equations? <br>-5x-3y=7<br>-3x-4y=2

garri49 [273]

Answer:

(-2, 1)

Step-by-step explanation:

Systems of equations can be solved using different methods. For this set of systems, you can multiply each equation by a factor in order to eliminate a variable and solve for the other variable:

-3(-5x - 3y = 7) or 15x + 9y = -21

5(-3x - 4y = 2) or <u>-15x -20y = 10</u>

-11y = -11

y = 1

Solve for x: -5x - 3 = 7

Add 3 to both sides: -5x -3 + 3 = 7 + 3 or -5x = 10

Solve for x: x = -2

(-2, 1)
