Answer:
x = - 7, y = - 2
Explanation:
given the system of equations
y = 3x + 19 → (1)
y = 5x + 33 → (2)
substitute y = 5x + 33 into (1)
5x + 33 = 3x + 19 ( subtract 3x from both sides )
2x + 33 = 19 ( subtract 33 from both sides )
2x = - 14 ( divide both sides by 2 )
x = - 7
substitute x = - 7 into either of the 2 equations to solve for y
substituting into (1)
y = 3(- 7) + 19 = - 21 + 19 = - 2
solution is x = - 7 , y = - 2
