Question

how do I solve this

20x + 9y = 535
​

Answer 1

Answer:

Simplifying 544 = 9 + 9y Solving 544 = 9 + 9y Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-9y' to each side of the equation. 544 + -9y = 9 + 9y + -9y Combine like terms: 9y + -9y = 0 544 + -9y = 9 + 0 544 + -9y = 9 Add '-544' to each side of the equation. 544 + -544 + -9y = 9 + -544 Combine like terms: 544 + -544 = 0 0 + -9y = 9 + -544 -9y = 9 + -544 Combine like terms: 9 + -544 = -535 -9y = -535 Divide each side by '-9'. y = 59.44444444 Simplifying y = 59.44444444

Answer 2

Answer:

5xy + 20x - 9y - 36 =>(5xy +20x) + (-9y - 36) =>5x(y + 4) -9(y + 4) =>(y+4) (5x - 9)
