The solution pair is (-7, 22), demonstrated as follows: (1) x + y = 15 : given; (2)4x + 3y = 38 : given; (3)3x + 3y = 45 : equation (1), multiplied by 3; (4) x = -7 : equation (2), minus equation (3); (5) y = 22 : equation (1), minus equation (4).
Technically there are no variables in this equation, as 47 minus 25 is equal to x (22)
To make 24 using 22, 9, 5, and 13, you can use the following equation: (22 - 9) + (13 - 5) = 24. This equation breaks down as follows: 22 minus 9 equals 13, and 13 minus 5 equals 8. Adding 13 and 8 together gives you 24.
if u minus 59 from 81 you get 22
-9h - 6 + 12h + 40 = 22 ie 3h = 22 + 6 - 40 h= -12/3 = -4
