That is in simplest form already, but in decimal form, it is 0.3
Given:
An equation in a coincidental system of two linear equations:
2x + 3y = -27
The other equation is
_y = _x - 102
Rearrange the second equation to be identical to the first
_y - _x = -102
Determine the factor, -102/-27 = 3.78
for x, 2 * 3.78 = 7.56
for y, 3 * 3.78 = 11.33
The second equation, 11.33y - 7.56x = -102
Answer: 0.194
Step-by-step explanation:
First step is to open the brackets.
7(19 - 9))/(4 * 5 * 18) = (133 - 63)/360
= 70 / 360
= 0.194
