Answer:

x-7=0

Step-by-step explanation:

We have two different methods to solve this question and we will still arrive at the same answer

The first method is

6x=42

Let'sdivide both sides by 6

x=7

Substrate 7 from both sides

x-7=0

The second method is

6x=42

Substrate 42 from both sides

6x-42=0

Factorise

6(x-7)=0

6=0

X-7=0

Therefore the final answer is x-7=0

Answer:

A) [tex]x-7=0\\[/tex]

Step-by-step explanation:

[tex]6x=42[/tex]

FIRST ANSWER CHOICE:

[tex]x-7=0\\[/tex] is equivalent to [tex]6x=42[/tex].

Mutiply both sides by 6:

[tex]6(x-7)=6(0)[/tex]

[tex]6x-42=0[/tex]

[tex]6x=42[/tex]

SECOND ANSWER CHOICE:

The equation [tex]4x2=14[/tex] , there is no symbol to seperate [tex]4x[/tex] and [tex]2[/tex] so I can guess it is mutiplication or [tex]8x=14[/tex] . That is not the answer

THIRD ANSWER CHOICE:

The equation x - 1 = 8 cannot be the answer:

x - 1 = 8

[tex]6(x) - 6(1) = 6(8)[/tex]

[tex]6x-6=48[/tex]

[tex]6x=54[/tex]

FOURTH ANSWER CHOICE:

The equation [tex]6x-1=23[/tex] cannot be the answer:

[tex]6x-1=23[/tex]

[tex]6x=24[/tex]
