System of eqns
<span>
2x + y = −4 and
y = 3x + 2
substituting second eqn into 1st
2x + (3x + 2) = -4
2x + 3x = -4 - 2
5x = -6
x = -6/5
y = 3*(-6/5) + 2 = (-3*6 + 2*5)/5 = (-18 + 10)/5
= -8/5
</span><span>negative 6 over five comma negative 8 over 5 </span>
2x+3x+2=-4(cause y=3x+2)
5x=-6
x=-6/5
f(-6/5)=-8/5
negative 6 over 5
