3x-4y=12
5x-2y=-8
I need the steps and answer to this equation.

(-4,-6)

Step-by-step explanation:

3x-4y=12

5x-2y=-8

multiply #2 by "-2"

3x-4y=12

-10x-4y=16

add two equations

-7 x = 28

x= -4

plug in -4 to equation (1 or 2)

-12 - 4y = 12

-4y = 24

y = -6

(-4,-6)

x = -4.

y = -6.

Step-by-step explanation:

3x-4y=12

5x-2y=-8       Multiply this equation by 2:

10x-4y = -16    Subtract this from the first equation:

-7x  = 28

x = -4

Substitute thin in equation 2:

3*(-4)  - 4y = 12

-12 - 4y = 12

-4y = 24

y = -6.

probably .5

i can on others if necessary.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
