It was a debate between the northerners and southerners (forgive my spelling). The northerners feared the addition of more slave states and a corresponding lack of reprenestation of their intrests in the North. For the southern slave holders, new western lands would be a boon (helpful) to enslaved people and the Louisiana purchase threatened to entrench and expand their suffering to western territories.
I got this on Khan Academy
So first you are going to want simplify the left side of the “=“ sign by multiplying the number outside the parenthesis, 2, by the numbers inside the parenthesis, (x+10). So, 2*x= 2x and 2*10=20. Bringing you to 2x+20=20, from here you want to isolate the variable, 2x, so you have to subtract 20 from both sides to do so. This brings you to 2x=0, when a variable is equal to zero, in specific problems, like this one, it is right, but always make sure to check your answer because in some problems when the variable is equal to 0 the answer is sometimes No Solution, so be careful. The way you want to be sure that x=0 in this equation is the plug it into the original equation, 2(x+10)=20, so it would be, 2(0+10)=20 and this goes to 2(10)=20, multiply the outside number to the inside which gives you 20 so then 20=20. It matches so it’s correct, THE ANSWER IS x=0, sorry if I made it complicated.
I think the answer is c 24
