Answer:
Standard form of (ax + by = c) given equation is -3x + 3y = 3
Explanation:
Given equation: x + y + 3 = –2x + 4y
Standard form of equation: ax + by = c
Solution:
x + y + 3 = –2x + 4y
= -2x + 4y = x + y +3
By subtracting x and y from both sides of equation:
= -2x - x + 4y - y = x + y + 3 - x - y
= -3x +3y = 3
So standard form of equation is -3x + 3y = 3 in which -3 is a and 3 is b and 3 is equal to c.
