Question

-3x+7y=5x+2y
Solve for y
X=-5

Answer 1

Answer:

x=-5

y=.......

Step-by-step explanation:

-3x+7y=5x+2y

=-3(-5)+7y=5(-5)+2y

=-15+7y=-25+2y

=7y-2y=-25+15

=5y=-10

=y=-10/5

=y=-2

So, y=-2

PLEASE MARK TO BRAIN LIST

Answer 2

The equation provides us the value of x, which is -5. So first we need to give x it's value in the equation.

$-3x + 7y = 5x + 2y$

$(-3 * -5) + 7y = (5 * -5) + 2y$

$15 + 7y = (-25) + 2y$

Now we need to solve the equation ⇒ $15 + 7y = (-25) + 2y$

Let's solve your equation step-by-step.

$15 + 7y = (-25) + 2y$

Step 1: Simplify both sides of the equation.

$7y+15=2y-25$

Step 2: Subtract 2y from both sides.

$7y+15-2y=2y-25-2y$

$5y+15=-25$

Step 3: Subtract 15 from both sides.

$5y+15-15=-25-15$

$5y=-40$

Step 4: Divide both sides by 5.

$\frac{5y}{5}=\frac{-40}{5}$

$y=-8$

∴ $y=-8$ in the equation $-3x + 7y = 5x + 2y$ where $x=-5$.
