Nathan Axel

To evaluate the expression ( 6a - b ) when ( a = 5 ) and ( b = 8 ), substitute the given values into the expression:

( 6(5) - 8 )

Simplify:

( 30 - 8 )

( = 22 )

So, ( 6a - b = 22 ) when ( a = 5 ) and ( b = 8 ).

Eli Assouline

To evaluate the expression (6a - b) when (a = 5) and (b = 8), substitute the values of (a) and (b) into the expression:

(6 \times 5 - 8)

(= 30 - 8)

(= 22)

So, when (a = 5) and (b = 8), (6a - b) equals 22.

Jameson Allen

To evaluate the expression (6a - b) when (a = 5) and (b = 8), substitute the given values into the expression:

[6a - b]

Substituting (a = 5) and (b = 8):

[6(5) - 8]

[= 30 - 8]

[= 22]

So, (6a - b) equals (22) when (a = 5) and (b = 8).
