-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
17 plus 14 plus 8 equals.... 39 !
If 'n' is 8, then (2n - 7) is 9 .
A = 4 (7x4) + 8 = 36 (6x4) + 14 = 36

17 plus 14 plus 8 equals.... 39 !
If 'n' is 8, then (2n - 7) is 9 .
(-8) + (-8) + (+2) = -8 - 8 + 2 = -14

5m+n = 37 m-2n = 14 => m = 2n+14 Substitute the value of m into the top equation: 5(2n+14)+n = 37 10n+70+n = 37 10n+n = 37-70 11n = -33 Divide both sides by 11 to find the value of n: n = -3 Substitute the value of n into the original equations to find the value of m: Therefore: n = -3 and m = 8
A = 4 (7x4) + 8 = 36 (6x4) + 14 = 36
