I did some math and i got this

x = -2

Hello.

In order to solve the equation, we need to isolate x.

First, subtract 1 from both sides:

[tex]\mathrm{7x+1-1=8x+3-1}[/tex]

[tex]\mathrm{7x=8x+2}[/tex]

Now, subtract 8x from both sides:

[tex]\mathrm{7x-8x=8x-8x+2}[/tex]

[tex]\mathrm{7x-8x=2}[/tex]

[tex]\mathrm{-x=2}[/tex]

Now, the minus sign is the same as -1.

In order to isolate x, we need to multiply both sides by -1:

[tex]\mathrm{x=-2}[/tex]

Therefore, the answer is

[tex]\mathrm{x=-2}[/tex]

I hope it helps.

Have a nice day.
