Answer: the answer is 2x-3=15
Step-by-step explanation: It’s simple so whenever you see x in the equation you just plug 9 in it’s place for example:
equation 1: 2x-3=15 —> 2(9)=18-3= 15 for this equation 9 is the solution
equation 2: 4+5(9)=18 —> 4+45=49 and 49 does NOT equal to 18 therefor 9 is not a solution
equation 3: 3(9)+2= 29 and 29 does NOT equal to 25 so 9 is not the solution
equation 4: 81(9)-3=6 —> 726 does NOT equal to 6 so not a solution
equation 5: 24-2(9)=13–> 6 does not equal to 13 so 9 is not a solution
equation 6: 3(9)+7=8 —> 34 does not equal to 8 so 9 is not a solution
(hope this helps)
