Include all steps on how to solve the (remember the x are variables, they aren't multiplication signs) (5x2-3) + (2x2-3x3)

( 5x^2 - 3) + (2x^2 - 3x^3)

= 5x^2 - 3 + 2x^2 - 3x^3  Adding like terms:-

= -3x^3 + 7x^2 - 3 answer

2(10 - 13x) + 9x = -34x + 6020 - 26x + 9x = -34x + distributive property-17x = -34x + subtraction property (subtracted 20 from both sides)17x = addition property (added 34x to both sides)x = 40/ division property (divided both sides by 17)
