Solve the system with elimination.3x + y = 9x + 2y = 3
NikAS [45]

In order to solve by elimination, let's multiply the first equation by -2. This way, when we add the equations, the variable y will be canceled out:

\begin{cases}-6x-2y=-18 \\ x+2y={3}\end{cases}

Now, adding the equations, we have:

\begin{gathered} -6x-2y+x+2y=-18+3\\ \\ -5x=-15\\ \\ x=\frac{-15}{-5}\\ \\ x=3 \end{gathered}

Now, calculating the value of y, we have:

\begin{gathered} x+2y=3\\ \\ 3+2y=3\\ \\ 2y=0\\ \\ y=0 \end{gathered}

Therefore the solution is (3, 0).

In 1980, Ric was twice as old as Nancy who was as old as Manual. In 1992, Ric, Nancy and Manual’s ages added up to 78 years. How
myrzilka [38]
He was 21 in 1980,
There are twelve years in between them all so you subtract 36 from 78 and since he was double as old as Nancy, and Manual was the same age as her, you would divide 42 into two parts, Ric and the 10.5 year olds, and Ric would be 21 in 1980.
