You can put this solution on YOUR website! see its very simple juts follow me
2(2x-5)+ 4(5x+9)
2(2x-5) this will give you 4x - 10.wen u multiply 2 through the bracket
4(5x+9) this will give you 20x + 36.wen u multiply 4 through the bracket
so u ll have 4x - 10 + 20x + 36 so you take like terms and there u go your answer is: 24x + 26 because 4x + 20x =24x and -10 + 36 = 26.
hop u got that clearly.
