Question

Как будет решение 2x+4y-7=0

Answer 1

2x + -4y + -7 = 0
-7 + 2x + -4y = 0
-7 + 2x + -4y = 0
-7 + 2x + 7 + -4y = 0 + 7
-7 + 7 + 2x + -4y = 0 + 7
 -7 + 7 = 0
0 + 2x + -4y = 0 + 7
2x + -4y = 0 + 7
0 + 7 = 7
2x + -4y = 7
2x + -4y + 4y = 7 + 4y
-4y + 4y = 0
2x + 0 = 7 + 4y
2x = 7 + 4y

x = 3.5 + 2y

x = 3.5 + 2y
