Question

Y = 3.2 Solve the following system of equations by substitution. 3x -9x + 3y = 1

Answer 1

$\huge\text{Hey there!}$

$\huge\text{3x - 9x + 3y = 1}\\\huge\text{\boxed{\rightarrow} -6x + 3y = 1}\\\huge\text{\boxed{\rightarrow} -6x + 3(3.2) = 1}\\\huge\text{\boxed{\rightarrow} -6x + 9.6 = 1}$

$\huge\textsf{SUBTRACT \underline{\underline{9.6}} to BOTH SIDES}\\\huge\text{-6x + 9.6 - 9.6 = 1 - 96}\\\\\\\huge\textsf{DIVIDE \underline{\underline{-6}} to BOTH SIDES}\\\\\huge\boxed{\dfrac{-6\mathsf{x}}{-6}= \dfrac{-8.6}{-6}}$

$\huge\textsf{SIMPLIFY ABOVE \& YOU HAVE YOUR}\\\huge\textsf{RESULT OF THE X-VALUE}\\\\\\\boxed{\huge\boxed{\huge\textsf{x = \bf 1.433333 or } \mathsf{x = \bf \dfrac{8.6}{6}}}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}\\\\\\\\\boxed{\huge\boxed{\frak{Amphitrite1040:)}}}$

Answer 2

3x-9x+3(3.2)=1

3x-9x+9.6=1
-9.6. -9.6
-6x=-8.6
X=-8.6/-6=1.433333333
