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

How do I solve this using substitution?

x=1

y=3

Step-by-step explanation:

y=-3x+6

y=-6x+9

replace y with y

-3x+6=-6x+9

combine like variables

3x=3

x=1

substitute 1 for x to get y

y= -3(1)+6

y=3

1. y=3x+6 = x=

−1

3

y+2

2. y=-6x+9 = x=

−1

6

y+

3

2

Step-by-step explanation:

ITs easy

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..
