Question

b. r + 2y + 32 from 6x +423 +3=​

Answer 1

5x+2y=32 ----- (1)

6x+6y=42 ----- (2)

First use formula for cross multiplication method:

b1c2−b2c1x=c1a2−a1c2y=a2b2−a2b1−1

So, from equation (1) and (2) we can write the value of a, b and c.

2×42−6×32x=32×6−5×42y=5×6−6×2−1

84−192x=192−210y=30−12−1

108x=−18y=18−1

−108x=18−1

x=18108=6

−18y=18−1

y=1818=1

The solution is (6, 1)

Answer 2

Answer:

Let's simplify step-by-step.

6x+423+3−r+2y+32

=6x+423+3+−r+2y+32

Combine Like Terms:

=6x+423+3+−r+2y+32

=(−r)+(6x)+(2y)+(423+3+32)

=−r+6x+2y+458

Answer:

=−r+6x+2y+458
