Question

solve the equations 8a+45b=5, 12a-30b=1. If a = 1/3x-2 and b=1/4y+3 find x and y.​

Answer 1

If a = 1/3x - 2

b = 1/4y + 3

8a + 45b = 5

8 * 1/3x - 2 + 45 * 1/4y + 3 = 5

8/3x - 2 + 45/4y + 3 = 5

8 - 6x/3x + 45 + 12y/4y = 5

32y - 24xy + 135x + 36xy/12xy = 5

32y + 12xy + 135x/12xy = 5

32y + 135x + 12xy = 5 * 12xy

32y + 135x = 60xy - 12xy

135x = 48xy - 32y

x = 48xy - 32y/135

then,

y = 48xy - 135x/32
