Answer:
Step-by-step explanation:
Given system of equations
Solving as follows:
Simplify the second equation by dividing all terms by 3
- 3x+3y=-3 divide by 3
- ⇒ x + y = -1
Now, considering the coefficient of x of 5 in the first equation, we will multiply the simplified second equation by 5 and subtract from the first equation:
- x + y = -1 multiply by 5
- ⇒5x + 5y = -5
Subtract it from 5x + 4y = 2
- 5x + 4y - 5x - 5y = 2 - (-5)
- -y = 7
- y = -7
Finding x using simplified second equation:
- x + (-7) = -1
- x = - 1 + 7
- x = 6
Answer is (6, -7)
