Answer 1

Answer:

1. -3 × A1 + A2 --> B2

2. $-\frac{1}{7}$ × B2 --> C2

Step-by-step explanation:

1. -3 × A1 + A2 --> B2

(4x × -3) + 12x = -12x + 5x = -7x

(2y × -3) + 6y = -6y + 6y = 0y

(-10 × -3) + -9 = 30 - 9 = 21

2. $-\frac{1}{7}$ × B2 --> C2

-7x × $-\frac{1}{7}$ = 1x

21 × $-\frac{1}{7}$ = -3

Same process as last time
