Question

Given the system of equations,

Answer 1

Answer:

(3, 2)

Step-by-step explanation:

$\underline{+\left\{\begin{array}{ccc}x+2y=7\\x-2y=-1\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad2x=6\qquad\text{divide both sides by 2}\\.\qquad\qquad\boxed{x=3}\\\\\\\text{Put the value of x to the first equation:}\\\\3+2y=7\qquad\text{subtract 3 from both sides}\\2y=4\qquad\text{divide both sides by 2}\\\boxed{y=2}$
