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
