Answer:
(–19, 55)
Step-by-step explanation:
y = –3x – 2 equation 1
5x + 2y = 15 equation 2
using equation 1 in equation 2 we have:
5x + 2(–3x – 2) = 15
5x –6x – 4 = 15
-x = 15+4
x=-19
using equation 1:
y = -3(-19)- 2
y= 57-2
y= 55
If a fraction has 10 as its denominator, then we can write its decimal expansion by putting the decimal point after one number from the left.
Example:
If a fraction has 100 as its denominator, then we can write its decimal expansion by putting the decimal point after two numbers from the left.
