Answer 1

Hi,

Explanation:

Because the diagonals of a parallelogram intersect in the middle:

`\left\{\begin{array}{ccc}y&=&x+3\\y+1&=&3x+2\\\end {array} \right.\\\\\\\left\{\begin{array}{ccc}y&=&x+3\\x+3+1&=&3x+2\\\end {array} \right.\\\\\\\left\{\begin{array}{ccc}2x&=&2\\y&=&x+3\\\end {array} \right.\\\\\\\left\{\begin{array}{ccc}x&=&1\\y&=&4\\\end {array} \right.\\\\`
