So, students should be able to solve basic linear equations as shown above. The aim in order to solve the equation would be to get all of the x values onto one side of the equation and all of the integers...

2x + y = 6x - y = 6x = 6 + y => 2(6 + y) + y = 18 => 12 + 3y = 18 => 3y = 6 => y = 2x - (2) = 6 => x = 8x = 8, y = 2

16 teams. Therefore, 1 team plays (16-1)x2=30 matches in a season. Total matches played = 30+28+26+...+2+0. 16 teams so total number of matches = 16 x (30+0)/2 =240Or each team plays 30 matches. 30x16=480...

first combine into one ratio by finding lowest common multiple between common category so houses:flats:bungalow = 14:8:5. then for every 5 bungalows to every 14 houses so 50/5 = 10 and 10 x 14 = 140. so t...

Area of rectangle is 20 cm². The new area of the enlarged rectangle is the original area, 20 cm², times the area scale factor. We are only given the length scale factor, therefore, w...
