7z - 9.4 = 11.6
7z = 11.6 + 9.4 = 21
z = 21/7 = 3
7z+9 = 72 7z = 72-9 7z = 63 z = 9
x = Y + 7z
2z+9.75-7z=-5.15
7z + 6s + s = 7z + 7s This can then be factorised using 7 as the factor: 7z + 7s = 7(z + s)
The answer to 2Z plus 9.75 subtract 7Z subtract equals 14.90. This is a math problem.
4.2/7=0.6
If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30
z = -2
58 x 58 = 116 WRONG
7z - 3 = 11 + 3z ie 7z -3z = 11 + 3 4z = 14 z = 3.5 Check: (7 x 3.5) - 3; 11 + (3 x 3.5) 24.5 - 3 = 11 + 10.5 21.5 = 21.5 QED
It is: 928/8 = 116
Perhaps unsurprisingly there are exactly 116 days in 116 days.
