Answer 1

$\boxed{\begin{array}{lr}a)\\x + 2y = 3\\1+2y=3\\2y=3-1\\2y=2\\y=2/2\\y=1\\\end{array}}\\\\\boxed{\begin{array}{lr} b)\\x + 2y = 3\\2 + 2y=3\\2y=3-2 \\2y=1\\y = 1/2 \end{array}} \\ \\ \boxed{\begin{array}{lr} c)\\x+2y=3\\3+2y=3\\2y=3-3\\2y=0\\y=0/2\\y=0\\\end{array}}\\\boxed{\begin{array}{lr} d)\\x+2y=3\\3+2y=3\\2y=3-3\\2y=0\\y=0/2\\y=0\\\end{array}}\\\boxed{\begin{array}{lr} e)\\x+2y=3\\0+2y=3\\2y=3-\backslash\!\!\!0\\2y=3\\y=3/2\\\end{array}}$

$\boxed{\begin{array}{lr} f)\\x+2y=3\\-1+2y=3\\2y=3+1\\2y=4\\y=4/2\\y=2 \end{array}}$

Respostas;

$a=1\\\\b=\frac{1}{2}\\\\c=0\\\\d=2\\\\e=\frac{3}{2}\\\\f=2$
