Answer:

x=7

Step-by-step explanation:

3x+1=4x-6

take the x's in one side and the normal numbers on the other side.

3x-4x= -6-1

-x= -7

the substraction signs are crossed out, therefore

ans: x=7

Answer:

[tex]x=7[/tex]

Step-by-step explanation:

[tex]3x+1=4x-6[/tex]

Subtract 1 from both sides:

[tex]\longmapsto3x+1-1=4x-6-1[/tex]

[tex]\longmapsto3x=4x-7[/tex]

Subtract 4x from both sides:

[tex]\longmapsto[/tex] [tex]3x-4x=4x-7-4x[/tex]

[tex]\longmapsto[/tex] [tex]-x=-7[/tex]

Divide both sides by -1:

[tex]\longmapsto[/tex] [tex]\frac{-x}{-1}=\frac{-7}{-1}[/tex]

[tex]\longmapsto[/tex] [tex]x=7[/tex]
