Practice problem
Solve for aaa and bbb. {2(a+b)=4a−b=1\begin{cases} 2(a+b)=4\\ a-b=1 \end{cases}{2(a+b)=4a−b=1
a=53,b=23a=\frac{5}{3}, b=\frac{2}{3}a=35,b=32
a=32,b=12a=\frac{3}{2}, b=\frac{1}{2}a=23,b=21
a=2,b=1a=2, b=1a=2,b=1
a=75,b=25a=\frac{7}{5}, b=\frac{2}{5}a=57,b=52
Type a concept, like “slope” or “photosynthesis”.
