Question

1.5g+1.2+7.6g-5.71.5g+1.2+7.6g−5.7?

Answer 1

So first off, combine like terms

\(\color{white}{\sf{0=\color{tomato}{1.5g}+\color{lime}{1.2}+\color{tomato}{7.6g}+\color{lime}{5.7}}}\)

\(0=\color{white}{\sf{\color{cyan}{9.1g} + \color{lime}{1.2}+\color{lime}{5.7}}}\)
\(0=\color{white}{\sf{\color{cyan}{9.1g} + \color{violet}{6.9}}}\)

Next, we need to get \(\sf{\color{violet}{g}}\) by itself, and to do that we remove \(\sf\color{violet}{6.9}\) to both sides

\(\sf\color{white}{\color{violet}{6.9} = \color{cyan}{9.1g}}\)

Now, we divide by \(\sf\color{cyan}{9.1}\) on both sides to get \(\sf\color{cyan}{g}\) by itself
\(\sf\color{white}{\color{yellow}{0.758}=\color{cyan}{g}}\)
