Subtract 19c from each side: 31 = 7c - 74Add 74 to each side: 105 = 7cDivide each side by 7: 15 = cCheck: Does 19 x 15 + 31 = 26 x 15 - 74?ie 285 + 31 = 390 - 74?ie 316 = 316? Yes, job done.
If the temperature was -25°C and rose 19°C, it would reach a temperature of -6°C. If it then fell 8°C, the final temperature would be -14°C.
I didn't - but the history of standard measurement units goes back centuries. The drive to make all countries uses the SI units for trade, science and engineering is very recent and continuing. A parallel development is that of standard screw-threads and fastenings dimensions, pioneered particularly by the 19C British engineer Sir Joseph Whitworth.
The equation for magnetic force is: F = q(v × B) Thus; F = (1.60 × 10 -19C)(3 × 106 m/s)(2 T) = 9.6 × 10-13 N F = ma a = F/m = (9.6 × 10-13 N)/(9.11 × 10-31 kg) = 1.05 × 1018 m/s2

Camille Saint-Saens was a 19C French composer
Range is about -2C to 5C in winter, 14C to 19C in summer
There is no equation first of all because the given expression conveys no clue regarding destination or source......................?
If you want to look at it simply, an electron is -1 charge and a proton is +1 charge. If you want to use coulombs as the unit, one elementary charge is 1.60x10^-19. so an electron would be -1.60x-19C while a proton is +1.60x-19C.
