Hi Jessica; I am always happppppppy to helpppppp! FIRST NUMBER...x SECOND NUMBER...x+4x (x)+(x+4x)=78 x+x+4x=78 6x=78 Let's divide both sides by 6... (6x)/6=78/6 x=13 x+4x 13+4(13)=13+52=65 13+65=78 Nov 19 | Vivian L. Comment Comments Four times greater means four times as great. Nov 20 | Michael F. I understand what you are saying, but the two interpretations are not grammatically consistent. four times as great=4x four times greater=x+4x Nov 20 | Vivian L. Comment
I understand what you are saying, but the two interpretations are not grammatically consistent. four times as great=4x four times greater=x+4x Nov 20 | Vivian L.
Let the the first number be x and the second number be y y is 4 times greater than x, y=4x the sum is 78, x+y=78 Substitute.... x+4x = 78 add the x's... 5x = 78 divide by 5... x = 78/5 then ... x = 15.6 and ... y=4x... y = 62.4 solution: x = 15.6, y = 62.4 Alternatively, you can change them to proper fractions: x = 78/5 = 15 3/5 y = 312/5 = 62 2/5 Nov 19 | John M. Comment Comments Hi John; I understand your answer. However, I think four times grater than another number means x+4x, not 4x. Nov 19 | Vivian L. Comment
