8x + 336 = 336 + -3x
Reorder the terms:
336 + 8x = 336 + -3x
Add '-336' to each side of the equation.
336 + -336 + 8x = 336 + -336 + -3x
Combine like terms: 336 + -336 = 0
0 + 8x = 336 + -336 + -3x
8x = 336 + -336 + -3x
Combine like terms: 336 + -336 = 0
8x = 0 + -3x
8x = -3x
Solving
8x = -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
8x + 3x = -3x + 3x
Combine like terms: 8x + 3x = 11x
11x = -3x + 3x
Combine like terms: -3x + 3x = 0
11x = 0
Divide each side by '11'.
x = 0

2) 
3) Opposite sides of a parallelogram are congruent.
4) 
Nora's speed (5*8)m²/2h= 20 m²/h.
Zack's speed (4*9)m²/3h= 12 m²/h
Together for 1 h they paint (20+12) m²/h=32m²/h
Given area (10*12)m²=120 m²
120m² *1h/32m² = 3.75 h (3h 45 min) to paint 10m*12m together.
