How do you turn two six's into ten?

solmaris [256]

This type of problem is made to test to see if you can break apart addition problems to make it easier to add. In this one, we will break apart one of the 6's into 4 and 2. This gives us 6+4+2. Now 6+4= 10, so we made two 6's into 10+2.

Solve for c.<br> -c/2+43 = 50

noname [10]

$\huge\text{Hey there!}$

$\mathsf{-\dfrac{c}{2}+43=50}$

$\large\text{SUBTRACT 43 to BOTH SIDES}$

$\mathsf{-\dfrac{c}{2}+43-43=50-43}$

$\large\textsf{CANCEL out: 43 - 43 because that gives you 0}$

$\large\textsf{KEEP: 50 - 43 because it helps solve for the c-value}$

$\mathsf{50 - 43 = \bf 7}$

$\large\text{NEW EQUATION: }\mathsf{-\dfrac{c}{2}=7}$

$\large\textsf{MULTIPLY }\mathsf{\dfrac{2}{-1}}\large\textsf{ to BOTH SIDES}$

$\mathsf{\dfrac{2}{-1}\times-\dfrac{c}{2}= \dfrac{2}{-1}\times7}$

$\large\textsf{CANCEL out: your RIGHT SIDE of the equation because that gives}\\\large\textsf{you 1}$

$\large\textsf{KEEP: }\mathsf{\dfrac{2}{-1}\times7}\large\textsf{ because that helps solve for the c-value}$

$\uparrow\large\text{SIMPLIFY THE EQUATION ABOVE \& YOU HAVE YOUR}\\\large\text{C-VALUE}\uparrow$

$\boxed{\boxed{\large\text{ANSWER: \huge\bf c = -14}}}\huge\checkmark$
