Akua now --- x
Ama now ---- 4x
Akua in 10 years ---- x+10
Ama in 10 years ---- 4x+10
4x+10 = 2(x+10)
solve for x
Ama now ---- 4x
Akua in 10 years ---- x+10
Ama in 10 years ---- 4x+10
4x+10 = 2(x+10)
solve for x

let Ama's age be X and Akua's age be Y
first sentence
X=4Y.......(i)
second sentence
X+10=(Y+10)2......(ii)
substitute (i) into (ii)
4Y+10=2Y+20
collect like terms
4Y-2Y=20-10
2Y=10 divide both side by 2
2Y/2=10/2
Y=5
substitute Y into (i)
X=4*5
X=20
therefore Ama =20years and Akua=5years

2x =10
2 2
X=5
X =4x
4x +10=2(X+10)
4x+10 =2x+20
