$$4x+8=x+5+7x-4 $$

Like terms

$$4x + 8 = 8x + 1$$

Isolate x by getting the variable on one side, alone
Subtract 8x from both sides

$$-4x  + 8 = 1$$

Subtract 8 from both sides to isolate x

$$-4x = -7$$

Divide the entire equation by -4

$$x  = \frac{ -4 }{ -7 } \rightarrow x = \frac{ 4 }{ 7 }$$

Remember, a negative divided by a negative, is a positive

shadowlegendx · Answer

Let me correct that last equation

it should be,

$$x = \frac{ -7 }{ -4 } \rightarrow x = \frac{ 7 }{ 4 }$$
