Yes because they are all boys and they are all in the same year
ans is b...multiply eqn 1 by -2 and eqn 2 by 3
=》 -6x + 10y = 4...eqn 3
=》 6x + 3y = 9...eqn 4
add eqn 3 and 4...
=》13y = 13
=》y =1 and x = 1
Multiplying fractions is simple. You just multiply across so 7/3 x 2/3 is 14/9 and that is the simplest form.
Vertical line has no slope. so only look at the x value. x=-4.
The correct answer is <em><u>-0.6</u></em> which in fraction form is <u><em>-3/5</em></u>
Your answer is <u><em>C. -3/5</em></u>
