1) 5x-4y-13=3x-4y-11 2) 5x-4y=3x-4y-11+13 (Add 13 to both sides) 3) 5x-4y+4y=3x-11+13 (Add 4y to both sides) 4) 5x-3x=-11+13 (Subtract 3x from both sides (the -4y and +4y cancel each other)) 5) 2x=2 (subtract 5x-3x and add -11+13) 6) x=1 (Divide both sides by 2) x=1 y=0 or (1,0)
5x + -4y = 13 Solving -5x + -4y = 13 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4y' to each side of the equation. -5x + -4y + 4y = 13 + 4y Combine like terms: -4y + 4y = 0 -5x + 0 = 13 + 4y -5x = 13 + 4y Divide each side by '-5'. x = -2.6 + -0.8y Simplifying x = -2.6 + -0.8y Simplifying 3x + -4y + -11 = 0 Reorder the terms: -11 + 3x + -4y = 0 Solving -11 + 3x + -4y = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 3x + 11 + -4y = 0 + 11 Reorder the terms: -11 + 11 + 3x + -4y = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 3x + -4y = 0 + 11 3x + -4y = 0 + 11Combine like terms: 0 + 11 = 11 3x + -4y = 11 Add '4y' to each side of the equation. 3x + -4y + 4y = 11 + 4y Combine like terms: -4y + 4y = 0 3x + 0 = 11 + 4y 3x = 11 + 4y Divide each side by '3'. x = 3.666666667 + 1.333333333y Simplifying x = 3.666666667 + 1.333333333y

Step-by-step explanation:
Day 1 : 1/3 book
Day 2: 1/4 book
Day 3: 1/5 book
Day 4: 13 pages
Total days 1 through 3 = 1/3 + 1/4 + 1/5 = 20/60 + 15/60 + 12/60 = 47/60
Day 4 = 1 - 47/60 = 13/60
