Answer:
A (4x-12)
Step-by-step explanation:
Still think of PEMDAS: 8-4(-x=5)
a) Multiply -4(-x + 5)
* -4(-x) = 4x (remember a neg x neg = pos)
* -4(5) = - 20
b) Now it reads = 8 +4x - 20
c) put all like terms together
* 8 - 20 = -12
Answer:
, a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.
Step-by-step explanation:
y= 2x+1 is a linear equation
