Answer:

D.

[tex]4x + 1 = 8[/tex]

Step-by-step explanation:

fist you need to turn it to standard form

move the constant to the right

4x+1=8

will be

4x=8-1

then subtract

4x=7 the standard form is this

now just divide both side by 4

4x/4=7/4

4x/4 any expression divide by it self is equal to 1

so we have

x=7/4

the answer is x=7/4

the equation is for two actually

the first one is y1=4x+1

the the other is y2=8
