X/(y+7)
this is actually an equation let the 'sum' be x we are assuming r means are meaning = so x/6 = 7 x=42 so thats the answer
x/3 + 7 = 5 x/3 = -2 x = -6
x+7=y
7 + 2x = x + 10 so 2x - x = 10 - 7 x = 3
x-7
x+7
=7(x+s)
x + 7
28 + 35 = (4 x 7) + (5 x 7) = 9 x 7 = 63
7+(x+5)
6*(x + 7)
x + 7
the sum of means (___+____) so you will need to open parentheses after the 2 times. 2*(7+x) is the expression you are looking for.
(7 x 8) + (8 x 8) = 15 x 8 = 120
Consider sum of two number to be x+y=6 and x/y=7. On substitution, it is found that x=4.42 and y=1.58.
Suppose the two numbers are x and y. Then, the sum of THEIR reciprocals is 1/x + 1/y = y/xy + x/xy = (y + x)/xy = 7/25
