For which independent value do the equations generate the same dependent value?

nalin [4]

Answer:

$x = - 3$

Step-by-step explanation:

The equations given are:

$y_1=6x+10$

$y_2=4x+4$

For the equations to generate the same independent value, then

$y_1=y_2$

This implies that:

$6x+10 = 4x + 4$

Group similar terms to get:

$6x - 4x = 4 - 10$

Simplify to get:

$2x = - 6$

$x = - 3$

12) -6n – 20 = -2n +4(1 – 3n)<br> What’s the first step

EastWind [94]

Answer:

n = 3

Step-by-step explanation:

-6n - 20 = -2n + 4 (1-3n)

First distribute the 4 (1-3n)

-6n - 20 = -2n + 4 - 12n

Combine like terms on the right side

-6n - 20 = -14n + 4

Get 'n' on one side by adding -6n to both sides

-20 = -8n + 4

Subtract 4 to both sides

-24 = -8n

Divide -8 to both sides

3 = n
