Answer:
Step-by-step explanation:
Sharia law is based on the Islamic Holy book called the Qur'an
4x + 5y = -13
2(4x + 5y) = 2(-13)
8x + 10y = -26 (equation 1)
5x - 2y = -8
5(5x - 2y) = 5(-8)
25x - 10y = -40 (equation 2)
equation 1 + equation 2,
(8x + 10y) + (25x - 10y) = (-26) + (-40)
8x + 10y + 25x - 10y = -26 + -40
33x = -66
x = -2
substitute x = -2 into equation 1,
8x + 10y = -26
8(-2) + 10y = -26
-16 + 10y = -26
10y = -10
y = -1
The values of x and y are -2 and -1 respectively.
Look at the multiples of the two numbers and find the lowest one that matches e.g.
7 = 7, 14, 21, 28
4= 4, 8, 12, 16, 20, 24, 28
28 is the LCM of 7 and 4
Steps to solve:
x - 4 < 5
~Add 4 to both sides
x - 4 + 4 < 5 + 4
~Simplify
x < 9
