Answer: Yo

Step-by-step explanation: Changes made to your input should not affect the solution:

(1): "a2" was replaced by "a^2". 7 more similar replacement(s).

(2): Dot was discarded near "f.p". 2 more similar replacement(s)

Unauthorized use of the imaginary unit "i" or syntax error in complex arithmetic expression

.................. V

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)

Algebra I

  • Solving systems of equations using substitution/elimination

Explanation:

Step 1: Define Systems

-9x - y = -12

6x + y = 6

Step 2: Solve for x

Elimination

  1. Combine equations: -3x = -6
  2. Divide -3 on both sides: x = 2

Step 3: Solve for y

  1. Define equation: 6x + y = 6
  2. Substitute in x: 6(2) + y = 6
  3. Multiply: 12 + y = 6
  4. Isolate y: y = -6
