Answer: A. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.
System A :
-x - 2y = 7 ..........(1)
5x - 6y = -3 ..........(2)
If we multiply the first equation by 5, then we will get :
5(- x - 2y) = 5(7)
⇒ - 5x - 10y = 35 ........... (3)
Now the Sum of equation (2) and equation (3) is:
⇒ Sum :
Now if we replace the second equation in system A with this , then we will get the system B.
Solution of system B:
First we will take the second equation as there is only one variable 'y'. So, we will solve that equation for 'y'
Now for solving 'x', we will plug y= -2 into the first equation
So, the solution of system B is (-3, -2), that means the solution of both systems are same.
Step-by-step explanation:
Answer:
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
let Ama's age be X and Akua's age be Y
X=4Y.......
X+10=(Y+10)2......
4Y+10=2Y+20
4Y-2Y=20-10
2Y=10 divide both side by 2
2Y/2=10/2
Y=5
X=4x5
X=20
therefore Ama =20years and Akua=5years
