Step-by-step explanation:
We can set up an equations with the conditions we are given. Let's use x for the missing number.
2(x-4)=3(x+4)
2x-8=3x+12
-20=x
Answer:
see below
Step-by-step explanation:
2(x-4) =3(x+4)
sum is addition
difference is subtraction
2 is multiply by2
solve 2(x-4) =3(x+4) distribute on both sides
2x - 8 = 3x + 12 add 8 on both sides
2x = 3x + 20 subtract 3x on both sides
-x = 20 multiply by -1
x = -20
