Question

what is 5a−4>2a+8 , pls explain

Answer 1

$\large \boxed{ \sf5a−4>2a+8} \\ \boxed{ \sf5a - 4 - 2a - 8 > {2a} +8 - {2a} - 8}\\ \boxed{ \sf5a - 4 - 2a - 8 > \cancel{2a} +\cancel8 - \cancel{2a} - \cancel8} \\ \boxed{ \sf3a - 12 >0 } \\ \boxed{ \sf3a - 12 + 12 >0 + 12} \\ \boxed{ \sf3a - \cancel{ 12 }+ \cancel{12} >12 } \\ \boxed{ \sf3a >12 } \\ \boxed{ \sf \frac{3a}{3} > \frac{12}{3} }\\ \boxed{ \sf \frac{\cancel3a}{\cancel3} > \frac{12}{3} } \\\boxed{ \sf a > 4 }$

Hence,

• a : { 5, 6, 7, 8, ......}
