Answer 1

Step-by-step explanation:

3=2x+y

2x+y=3

y=3−2x

Simplifying

7p + 6q + 13s = 11

Solving

7p + 6q + 13s = 11

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-6q' to each side of the equation.

7p + 6q + -6q + 13s = 11 + -6q

Combine like terms: 6q + -6q = 0

7p + 0 + 13s = 11 + -6q

7p + 13s = 11 + -6q

Add '-13s' to each side of the equation.

7p + 13s + -13s = 11 + -6q + -13s

Combine like terms: 13s + -13s = 0

7p + 0 = 11 + -6q + -13s

7p = 11 + -6q + -13s

Divide each side by '7'.

p = 1.571428571 + -0.8571428571q + -1.857142857s

Simplifying

p = 1.571428571 + -0.8571428571q + -1.857142857s
