....

2x + 3 ≥ 21 + 4x = ....​

2x + 3 ≥ 21 + 4x

2x + 3 - 4x ≥ 21 + 4x - 4x

2x + 3 - 4x ≥ 21

2x + 3 - 4x - 3 ≥ 21 - 3

2x - 4x ≥ 21 - 3

( 2 - 4 ) x

= -2x

-2x ≥ 21 - 3

-2x ≥ 18

-2x ÷ ( -2 ) ≤ 18 ÷ ( -2 )

x ≤ 18 ÷ ( -2 )

x ≤ -18 ÷ 2

x ≤ -9

2x + 3 ≥ 21 + 4x
= 2x - 4x ≥ 21 - 3
= -2x ≥ 18
= x ≤ 18/ -2
= x ≤ -9

semoga membantu! [answer.2.content]
