4x + 6y = 8
5x – 4y = 25
a.
(0.5, –1.3)
c.
(3.96, 3.04)
b.
(3.96, –1.3)
d.
(0.05, 3.04)

The solution set for 4x + 6y = 8, 5x – 4y = 25
is (3.96, –1.3). Multiply 4x + 6y = 8 by 5: 20x + 30y = 40; Multiply 5x ? 4y = 25 by 4: 20x - 16y = 100; (20x - 16y = 100) - (20x + 30y = 40): -46y = 60; y = 60/-46; y = -30/23; y = -1.3 Solve for x: 4x + 6y = 8; 4x + 6(-30/23) = 8; 4x - 180/23 = 8; 4x = 8 + 180/23; 4x = 364/23; x = (364/23)/4; x = 364/92; x = 91/23; x = 3.96
