To solve the system of equations by elimination, we can multiply the second equation by 5 to get:
10x + 5y = 5
Now, we can add this equation to the first equation to eliminate the variable y:
(3x - 5y) + (10x + 5y) = 21 + 5
Combining like terms, we get:
13x = 26
Dividing by 13 on both sides, we get:
x = 2
Substituting this value of x into the second equation, we get:
2(2) + y = 1
4 + y = 1
y = -3
Therefore, the solution to the system of equations is (2, -3).
Answer: (2, -3)
Solve the system by either substitution or elimination.
3x−5y=212x+y=1(1 point)
