Find the solution of this system of equations. separate the x- and y-values with a comma. x - 2y = -29 and x - y = -11

Solve the following system using elimination:
{x - 2 y = -29 | (equation 1)
{x - y = -11 | (equation 2)

Subtract equation 1 from equation 2:
{x - 2 y = -29 | (equation 1)
{0 x+y = 18 | (equation 2)

Add 2 × (equation 2) to equation 1:
{x+0 y = 7 | (equation 1)
{0 x+y = 18 | (equation 2)
Collect results:
  {x = 7, y = 18

You need to divide 210 square inches by 35 inches and that’s going to give you 6 inches and that’s the length of the hypothenuse of the right triangle i hope that this you : )
