7x - 2y = -3 . . . (1)
14x + y = 14 . . . (2)
(1) x 2 => 14x - 4y = -6 . . . (3)
(2) - (3) => 5y = 20
y = 20/5 = 4
From (1); 7x - 2(4) = -3
7x - 8 = -3
7x = -3 + 8 = 5
x = 5/7
Solution = (5/7, 4)
Step-by-step explanation:
3/4 + 1/2= 3+2/4= 5/4

Answer:
the answer is 25.3
Step-by-step:
22/5 * 23/4 = 22*23 over 5*4 = 506/20 = 253*2 over 10*2 that equals 253/10 now divide 253 by 10 and we get<em><u> 25.3!</u></em>
Answer:
Euclid introduced the axiomatic
Step-by-step explanation:
(79 + 94 + 91 + 92 + x) / 5 > = 90
(356 + x) / 5 > = 90
356 + x > = 90 * 5
356 + x > = 450
x > = 450 - 356
x > = 94 <=== Sherman can get the lowest score at 94
