Question

9 - 4x + 3y; x = 8 and y =3

Answer 1

We have the following expression given:

`9-4x\text{ +3y}`

We have some conditions given:

`x=8,\text{ y= 3}`

Then we just need to replace these conditions into the equation and we got:

`9-(4\cdot8)+\text{ (3}\cdot3\text{)= 9}-32+9=18-32=\text{ }-14`
