Because there was a pay rise, we can write the equation as x+0.04x = 24.492 and solve for x.
x+0.04x = 24.492
1.04x = 24.492
x=23.55
His original pay was £23.55
IT WOULD BE "D" I BELIEVE
HOPE IM RIGHT AND THIS HELPS
Here is the equation:
![x+(x+3)=11](https://tex.z-dn.net/?f=x%2B%28x%2B3%29%3D11)
⇒
![x+x+3=11](https://tex.z-dn.net/?f=x%2Bx%2B3%3D11)
You need to get "x" by itself so minus 3 from each side
![x+x+3-3=11-3](https://tex.z-dn.net/?f=x%2Bx%2B3-3%3D11-3)
⇒
![x+x=8](https://tex.z-dn.net/?f=x%2Bx%3D8)
⇒
![2x=8](https://tex.z-dn.net/?f=2x%3D8)
Divide 8 by 2
![8](https://tex.z-dn.net/?f=8)
÷
![2=4](https://tex.z-dn.net/?f=2%3D4)
x=4
So each 4 is equivalent to 4
Lets check:
![4+(4+3)=11](https://tex.z-dn.net/?f=4%2B%284%2B3%29%3D11)
⇒
![4+4+3=11](https://tex.z-dn.net/?f=4%2B4%2B3%3D11)
⇒
![11=11](https://tex.z-dn.net/?f=11%3D11)
So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7
