Answer:

x=4, y=-3. (4, -3).

Step-by-step explanation:

5x+4y=8

2x-3y=17

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

2(5x+4y)=2(8)

-5(2x-3y)=-5(17)

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

10x+8y=16

-10x+15y=-85

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

23y=-69

y=-69/23

y=-3

5x+4(-3)=8

5x-12=8

5x=8+12

5x=20

x=20/5

x=4

Solve the equation. <br><br><br> 12=2+z/-6

Bogdan [553]

Answer:

$\boxed{\bold{z=-60}}$

Step-by-step explanation:

Switch Sides

$\bold{2+\frac{z}{-6}=12}$

Subtract 2 From Both Sides

$\bold{2+\frac{z}{-6}-2=12-2}$

Simplify

$\bold{\frac{z}{-6}=10}$

Multiply Both Sides By -6

$\bold{\frac{z\left(-6\right)}{-6}=10\left(-6\right)}$

Simplify

$\bold{z=-60}$
