Step-by-step explanation:
Hey there!!
You can simply do it.
Here, -3x -6 +(-1) is given.
In this question, the like term is "-6" and "-1" because both are coefficients.
Combine it.
= -3x -6 -1 { as (-) (+)=(-)}
= -3x -7 { when there is (-) sign then it will be added but the sign would be minus}.
Or you can also write it as -( 3x+7). {taking (-) common}
Hope it helps...
