Answer:
Not a solution.
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define
[tex]\left \{ {{2x+5y=8} \atop {3x-2y=5}} \right.[/tex]
(-1, 2)
Step 2: Substitute and Check
- Substitute: [tex]\left \{ {{2(-1)+5(2)=8} \atop {3(-1)-2(2)=5}} \right.[/tex]
- Multiply: [tex]\left \{ {{-2+10=8} \atop {-3-4=5}} \right.[/tex]
- Combine: [tex]\left \{ {{8=8} \atop {-7=5}} \right.[/tex]
We see here that -7 ≠ 5. Therefore, (-1, 2) is not a solution of the systems of equations.
