Monday, 13 September met Gala was held in 2021.

right angles are formed by perpendicular lines. if the lines would extend, to make two intersecting lines, they would form four right angles.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
