Answer:
Step-by-step explanation:
3(8x - 5) + 10(10 - x) = 3*8x - 3*5 + 10*10 - 10* x
= 24x - 15 +100 -10x
= (24x -10x ) -15 +100
= 14x + 85
When two terms are in different sign, then subtract and put the bigger number's sign in the result
Here distribution property is used:
a*(b+c) = a*b + a*c
a*(b-c ) = a*b - a*c
