47 E + 33 H + 20 M = 15 (11) 0 = 0 (12) 0 = 0 (13)Question solving process: Multiply both sides of equation (1) by 47, the equation can be obtained: 47 A + 47 B + 47 C + 47 D + 47 E = 47 (14), then subtract both sides of equation (14) from both sides of...
47 E + 33 H + 20 M = 15 (11) 0 = 0 (12) 0 = 0 (13)解题过程:将第(1) 等式两边 乘以47后,可以得到等式: 47 A + 47 B + 47 C + 47 D + 47 E = 47 (14),然后再同时用第 (4) 等式两边 减去 等式(14)两边,方程组化为: A + B + C + D + E = 1 (1) F + G + ...
