- Solving systems of equations using substitution/elimination
Step-by-step explanation:
Step 1: Define Systems
-9x - y = -12
6x + y = 6
Step 2: Solve for x
Elimination
- Combine equations: -3x = -6
- Divide -3 on both sides: x = 2
Step 3: Solve for y
- Define equation: 6x + y = 6
- Substitute in x: 6(2) + y = 6
- Multiply: 12 + y = 6
- Isolate y: y = -6

The symbol "i" is only allowed in complex arithmetic, for example:
(3/5+7i)+(0.3-7.002i)
(5+77i)-(19/4-8i)
(240-22i)*(247/7+2.222i)
(33/5+99i)/(33/5-88i)
