Question

What is the solution to the linear equation?
6k + 10.5 = 3k + 12


k = 0.5
k = 2
k = 7.3
k = 9

Answer 1

\(6k+10.5=3k+12\)
The first thing we do is subtract 3k from both sides
which should give us \(3k=1.5\)
because \(3k+10.5−10.5=12−10.5\) and 12-10.5=1.5
so we get \(3k=1.5\)
then we ÷3 to both sides of the equation
\(\LARGE\frac{3k}{3}=\frac{1.5}{3}\)

\(\cancel{\frac{3k}{3}}=\frac{1.5}{3}\) (3k/3 cancels)
all that is left is \(\frac{1.5}{3}\)
so \(\frac{1.5}{3}=?\)
k=?
