Simplify each expression. me . 1,,2,3

  1.) 5(6x)= this is also known as 5 x 6x = 30x

2.)   2x + 5y + 7x = like terms are 2x and 7x so they are both posotive so u add them its is 9x

just so u know 5y u leave out 5y because it has no like term in the4 expression.

final answer= 9x + 5y

3.) 4(2x+5y): u use distributive property so 4(2x) or 4 x 2x = 8x

and 4(5y) or 4 x 5y= 20y  

final answer = 8x + 20y

i need the table so i can see

step-by-step explanation:

thats not a system of equations, that is a solution
