If 3x+54+(65 × 32)+ 902- (43/12) =y, then what is y?

IceJOKER [234]

Answer:

We cannot solve without a value for x. The simplified form is $3x+\frac{36,389}{12} =y$

Step-by-step explanation:

If the equation is $3x+54+(65)(32)+902-\frac{43}{12}=y$ then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

$3x+54+(65)(32)+902-\frac{43}{12}=y \\3x+54+2,080+902-\frac{43}{12}=y \\3x+3,036-\frac{43}{12}=y \\3x+\frac{36,432}{12} -\frac{43}{12} =y\\3x+\frac{36,389}{12} =y$
