X=12
Substitute y with 0
Multiply both sides
0=-3/4x+9
0=-3x+36
3x=36
Divide by 3
It’s 12
Answer:

Step-by-step explanation:
We have been given an expression
. We are supposed to combine like terms for our given expression.
We can see that
are like terms as both of these terms have x variable.
Similarly,
are like terms as both are constant.
Upon combining like terms, we will get:


Therefore, our required expression would be
.
Answer:
Step-by-step explanation:
Here is the workings
2x+4y+6+2y-5+3x combine like terms
2x+3x+4y+2y+6-5
Step 2
2x+3x+4y+2y+6-5 Add the similar exponents
5x+4y+2y+6-5
5x+6y+6-5
Step 3
5x+6y+6-5 Add and subtract
Your answer would be 5x+6y+1
Options C, D, E. You should be able to simplify each one and realise that CDE does not equal the given equation
