Let "x" be the "unknown number" for which we are to solve.
8x − (-54/9) = -18 ; Solve for "x" ;
→ 8x − (-6) = - 18 ;
→ 8x + 6 = - 18 ;
Subtract "6" from each side of the equation:
→ 8x + 6 − 6 = - 18 <span>− 6 ;
to get: 8x = -24 ;
Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the equation ; & to solve for "x" ;
8x / 8 = -24 / 8 ;
to get: x = -3 .

Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4
The answer is negative 2.5 why because...
