Step-by-step explanation:
Answer:
a)7, b)-40
Step-by-step explanation:
a) 5(x-1)=30
=>5x -5=30
=>5x=30+5
=>5x=35
=>x=35/5
so, x=7
b)3(x+10)-2(x-5)=0
=>3x+30-2x+10=0
=>x+40=0
so,x=-40
Step-by-step explanation:
The distributive property is as follows :
....(1)
We need to solve
using distributive property
Applying property (1) on the LHS of given equation
Taking a = 24, b = d/4 and c = -5
So,

So, we get the value of d as 6 using distributive property.
