Answer :
Answer:
x = 2 , y = 3
Step-by-step explanation:
given the system of equations
2x + 5y = 19 → (1)
y = 3x - 3 → (2)
substitute y = 3x - 3 into (1)
2x + 5(3x - 3) = 19 ← distribute parenthesis on left side and simplify
2x + 15x - 15 = 19
17x - 15 = 19 ( add 15 to both sides )
17x = 34 ( divide both sides by 17 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (2)
y = 3x - 3 = 3(2) - 3 = 6 - 3 = 3
The solution is x = 2 , y = 3
