Step-by-step explanation:
The given expression is :
2d+11-5d-4
It can be written as :
2d+11-5d-4 = 2d+11+(-5d)+(-4)
Taking like terms together,
= 2d+(-5d)+11+(-4)
Taking d common from above expression :
= d(2+(-5))+11+(-4)
= d(-3)+7
We know that, a(x) = ax
= -3d+7
Hence, these are the required steps.
