Answer:
The value of given expression = - 5mx
Step-by-step explanation:
Given expression;
10xm - 8mx + 6xm - 13xm
Find:
The value of given expression
Computation:
⇒ 10xm - 8mx + 6xm - 13xm
Step 1 ;
Rearrange expression;
⇒ 10mx - 8mx + 6mx - 13mx
Step 2 ;
Adding all terms
⇒ 10mx + 6mx - 8mx - 13mx
Step 3 :
Subtract term
⇒ 16mx - 21mx
⇒ -5mx
The value of given expression = - 5mx
