x+7
6*(x + 7)
If: 2x+8 = 7 then x = -1/2
=7(x+s)
Call your number "x", write an equation, and solve it: 8x = x + 49 7x = 49 x = 7
x+7=y
X+y
37,594 in expanded notation as the sum of multiplication expressions is: (3 x 10000) + (7 x 1000) + (5 x 100) + (9 x 10) + (4 x 1)
7-x
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
X/(y+7)
x + y = 28 x*y = 7 x=7/y replacing X in eq 1 7/y+y=28 y^2 - 28y + 7 = 0 using above solutions find the reciprocal and sum -- Dhruv
(x+y)+3
X+16 < 32
Suppose the smaller number is x, then the bigger number is x+7 Their sum is 123 ie x + (x+7) = 123 or 2x + 7 = 123 or 2x = 123 - 7 = 116 so that x = 58 and then x+7 = 65 The two numbers are 58 and 65
7 x 7 x 7 x 7 = 2,401 (standard notation).
x+5=7 -5 -5 x=2
