Question

What is 2.3(x – 2) = 15

Answer 1

$\huge\textsf{Hey there!}$

$\mathsf{2.3(x - 2) = 15}$

$\mathsf{2.3(x) + 2.3(-2) = 15}$

$\mathsf{2.3x - 4.6 = 15}$

$\large\textsf{ADD 4.6 to BOTH SIDES}$

$\mathsf{2.3x - 4.6 + 4.6 = 15 + 4.6}$

$\large\textsf{CANCEL out: -4.6 + 4.6 because it gives the number 0}$

$\large\textsf{KEEP: 15 + 4.6 because that helps solve find the x-value}$

$\mathsf{15 + 4.6 = \boxed{\bf 19.6}}$

$\large\textsf{NEW EQUATION: 2.3x = 19.6}$

$\large\textsf{DIVIDE 2.3 to BOTH SIDES}$

$\mathsf{\dfrac{2.3x}{2.3}=\dfrac{19.6}{2.3}}$

$\large\textsf{CANCEL out: }\mathsf{\dfrac{2.3}{2.3}}\large\textsf{ because that gives you 1}$

$\large\textsf{KEEP: }\mathsf{\dfrac{19.6}{2.3}}\large\textsf{ because that gives you the value of x}$

$\mathsf{\dfrac{19.6}{2.3}= \boxed{\bf x}}$

$\mathsf{\boxed{\bf x}=\dfrac{19.6}{2.3}}$

$\boxed{\bf {x = 8.521739}}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf x = 8.521739}}}\huge\checkmark$

$\large\textsf{Good luck on your assignment and enjoy your day!}$
