unknown values: x+3
equation: (x-3)+(x-2)+(x-1)+x+(x+1)+(x+2)+(x+3)=434
answer: 65
the greater of two numbers is 9 more than the smaller. if the smaller is added to twice the greater the result is 22. find both numbers
unknown values: g,s
equation: g = 9 + s
equation: 2*g + s = 22
answer: {31/3; 4/3} | {10.333; 1.333}
One number plus twice another number gives a sum of 42. The difference of these same two numbers equals �C3.Find the two numbers
unknown values: a,b
equation: a + 2*b = 42
equation: a - b = -3
answer: {12; 15}
