Answer:
thus the father is 64 years and son is 37years
Step-by-step explanation:
Let father be X and son be y
X=27+Y...........(I)
X-10=2(Y-10)
putting the value of X from eqn(I)
27+Y-10=2Y-20
Y+17=2Y-20
17+20=2Y-Y
37=y
X=27+Y
X=64

Answer:
x=2
Step-by-step explanation:
28−(3x+4)=2(x+6)+x
We need to use the distributive property for the right side.
28−3x−4=(2)(x)+(2)(6)+x)
28−3x−4=2x+2+x
−3x+24=3x+12
From here we need to subtract 3x from both side.
−3x+24−3x=3x+12−3x
6x+24=12
Transfer +24 on the right side.
6x=12−24
6x=−12
Finally, divide both sides by −6
6x/-6 = -12/-6
x=2
