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.
