Question

-7x + 3 = -15/2

Solving Equations Containing Fractions

Answer 1

subtract 3, divide by \(-7\)

Answer 2

\[-7x+3=-\frac{15}{2}\]
\[-7x=-\frac{15}{2}-3=-\frac{21}{2}\]
\[x=-\frac{21}{2}\times \frac{1}{-7}=\frac{3}{2}\]

Answer 3

why did you subtract 3

Answer 4

because you had \(-7x+3\) on one side of the equal sign, and you wanted to get \(x\) by itself

Answer 5

in order to get rid of the \(3\) you have to subtract it from both sides
like for example if you had
\[x+3=8\] then you know \[x=5\] becaues \(5+3=8\) or because \(8-3=5\)
