Rearrange the first equation2x + y = 20take away 2x from both sidesy = 20 - 2x substitute this y value into the second equation6x - 5(20 - 2x) = 126x -100 +10x = 12add 100 to both sides6x + 10x = 11216x = 112divide both sides by 16 x = 7Substitute this x value into the first equation to get y.2(7) + y = 2014 + y = 20take away 14 from both sidesy = 6
So, y = 6 and x = 7
Answer:
y = -3x + 7
