H=150m
P=190x
5=m+x
P=H+270
P stands for Polish
H stands for Hungarian
M stands for the time she can speak in H
X stands for the time she can speak in P
Plug in H and P
190x=150m+270
5=m+x
Solve for X
-m both sides
X=-m+5
Plug in x
190 (-m+5)=150m+270
Distribute
-190m+950=150m+270
+190m both sides
950=340m+270
-270 both sides
680=340m
÷340 both sides
M=2
5=x+2
-2 both sides
X=3
She spoke 2 minutes in Hungarian and 3 minutes on Polish
