The question says: 4(x) +3 = 2(x) + 9 so now you need to find x first you should add -2(x) on both sides of the equation and then add -3 on both sides: 4(x) - 2(x) = 9 - 3 2(x) = 6 now you can divide both sides by 2: x = 6/2 x = 3 :))) I hope this is helpful have a nice day
Four times a number (we are gonna make that be "x") increased by 3 would be 4x+3 it says it is the same as (means it is equal to) twice the number (2x) increased by 9 (+9) so the full equation would be 4x+3=2x+9 You have to solve for the number (x). 4x+3=2x+9 -2x -2x (Have to get the x's to one side) 2x+3=9 -3 -3 (you have to get the numbers on one side too) 2x=6 /2 /2 (to get x alone) X=3 (the number is 3)
C=8h+12 the 8h represents the $8 per hour for renting the boat, and h represents however many hours you rent the boat for. The +12 is the initial $12 fee. This is in slope intercept form, just using different variables than y=mx+b
