Solve for y in 3x+7=y
y=7−3x
Substitute y=7−3x
y=7−3x into 8x−3y=30
8x−3y=30.
17x−21=30
Solve for x
x in 17x−21=30
17x−21=30.
X=3
Substitute x=3 into y=7−3x
y=-2
Therefore,
x=3
y=−2
Subtract 12x from 84x = 72x

Answer:
-3 is the coefficient of c.
Step-by-step explanation:
The given expression is :
9a³ + 4b² - 3c + 11
We need to find the term with coefficient -3 in the expression.
The coefficient is defined as a number or quantity placed with a variable.
The coefficient of a³ = 9
The coefficient of b² = 4
The coefficient of c = -3
Hence, -3 is the coefficient of c.
