Twice a number increased by seven is equal to five. which of the following represents the equation and solution for this statement?

2n + 7 = 5; n = -4.5
2n = 7 + 5; n = 6
2(n + 7) = 5; n = -4.5
2n + 7 = 5; n = -1

Remember, you can do anything to an equation as long as you do it to both sidesminus 36 from both sides4.5(8-x)=66-2.5(3x+24)distribute36-4.5x=66-7.5x-60add like terms36-4.5x=-7.5x+6add 7.5x to both sides36+3x=6minus 36 from both sides3x=-30divide both sides by 3x=-10
