Solve the system.<br> 2x+y = 3<br> -2y = 14 - 6x

bezimeni [28]

Answer:

The solution is: (2, -1)

Step-by-step explanation:

First we rewrite the second system equation

$-2y = 14 - 6x$ → $6x-2y=14$

Now we have the following system of equations:

$2x+y = 3$

$6x-2y=14$

To solve the system multiply the first equation by -3 and add it to the second equation

$-6x+-3y = -9$

$6x-2y=14$

--------------------------------------

$0-5y=5$

$y=-1$

Now we substitute the value of y in the first equation and solve for x

$2x-1 = 3$

$2x= 4$

$x= 2$

The solution is: (2, -1)

Please help someone!!!

Answer:

$x = 25$

Step-by-step explanation:

$(4x) + (5 + 3x) = 180$

$4x + 5 + 3x = 180$

$7x + 5 = 180$

$7x = 180 - 5$

$7x = 175$

$\frac{7x}{7} = \frac{175}{7}$

$x = \frac{175}{7}$

$x = 25$
