Answer:
<h3>X=5/31=0.16</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
4x+27x=31x (Combine like terms, group like terms, & Add.)
31x=5
31x/31=5/31 (Divide by 31 from both sides.)
5/31=0.16
x=5/31=0.16
In conclusion, the correct answer is x=5/31=0.16.

<h3>
Answer: 49</h3>
Work Shown:
Replace x with 3, replace y with -8. Use order of operations PEMDAS to simplify.
x^2 + y^2 + x*y
3^2 + (-8)^2 + 3*(-8)
9 + 64 - 24
73 - 24
