Answer: A coefficient refers to a number or quantity placed with a variable
Step-by-step explanation: For example, in the expression 3x, 3 is the coefficient but in the expression x2 + 3, 1 is the coefficient of x2. In other words, a coefficient is a multiplicative factor in the terms of a polynomial, a series, or any expression.
Answer:
x=4
Step-by-step explanation:
Answer:
x = 10, y = 5
Step-by-step explanation:
Substitute the second equation into the x value of the first equation.
-4x + 11y = 15
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15
y = 5
Now substitute the y value into an original equation.
x = 2y
x = 2(5)
x = 10
