since this is way easier here are just the rest of the questions. please write them all in slope-intercept form. 11. -3x + 2y = -4 | 12. x + 3y = 9 | 13. 3x - 5y = 20 | 14. 3x - y = 1 | 15. 5x + 4y = 0| good night i hope you guys sleep well!

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
