Let x=aunt's agethen x-14=Mrs West's ageso we have:60-(x-14)=x-40 simplify60-x+14=x-40 subtract x from each side and also subtract 60 and 14 from each side60-60-x-x+14-14=x-x-40-60-14 collect like terms
-2x=-114x=57------------aunt's agex-14=57-14= 43----------Mrs West's ageck60-43=57-4017=17
Step-by-step explanation:
Substitute the value x for any number, for example x=1, you substitute x for the value 1, so this is the final equation: y= -3(1)+5 and the answer you get is the value of y. Continue substituting x for any value in the graph of course and then write the answer for y which is the number you get by solving the equation. Then plot the graph with the points you got. Hope this helps, let me know if you need more help :)
