Answer:
x=4
Step-by-step explanation:
First set the equation equal to 4:
-2x +12=4
Subtract 12 from both sides:
-2x +12=4
-12 -12
-2x=-8
Then divide each side by -2 to isolate the x:
-2x/-2=-8/-2
x=4
Answer:
f, s={36,6} is your answer.
Step-by-step explanation:
PREMISES
6s+9=3(s+9)
ASSUMPTIONS/SUFFICIENT CONDITION(S)
Let the son's current age s=s
Let the father's current age f=6s
CALCULATIONS
6s+9=3(s+9)
6s+9=3s+27
6s-3s+(9–9)=3s-3s+(27–9)
3s+0=0+18
3s=18
3s/3=18/3
s=
6
and,
if s=6, then
6s=
f=
36
PROOF
If f,s=36, 6, then the equations
6s+9=3(s+9)
6(6)+9=3(6+9)
36+9=3(15) and
45=45 establish the roots (zeros) f, s=36,6 of the mathematical statement 6s+9=3(s+9)
