The expression (4a + b) – 3(2a + b) is equivalent to:

-2a - 2b

Step-by-step explanation:

Question : (4a + b)-3(2a + b)

= 4a + b - 6a - 3b

= 4a - 6a + b - 3b

= -2a + (-2b)

= -2a -2b

If you need detail solution here ;

first + multiply both 4a and b

first -3 multiply both 2a and b and then -3×2a= -6a

-3×b = -3b

and it will be 4a + b -6a -3b,then collect like terms

4a - 6a + b -3b

= -2a +(-2b) in this part + tims - = -

= -2a - 2b
