The coefficient is a number before a variable.
Here, the coefficient is 9.
The like terms are any terms that have the same variable.
Here, 9k and -k are like terms, and 7 and 4 are like terms as well.
Combine like terms:
8k+3
The constants are: 7 and 4 (Constants are numbers in an expression or equation)
After combining like terms, the constant became
3
Anything less than 90, i hope this helps

Answer:
x = 2
y = 0
Step-by-step explanation:
To solve by elimination, you have to first change the equations so that you can cancel out one variable.
Change the second one.
4y = 24x - 48
Subtract them:
7x = -24x + 62
31x = 62
x = 2
y = 0
