Answer:
Step-by-step explanation:
11). 6x + 3y = 9
3(2x + y) = 9
2x + y = 3
y = -2x + 3
Since variables are of single degree therefore, it's a linear function
12). 3y - 2x = -2x - 12
3y - 2x + 2x = -2x - 12 + 2x
3y = -12
y = -4
Since variable y is of single degree therefore its a linear function.
13). 11y + 4x = -8 + 11y
11y + 4x - 11y = -8 + 11y - 11y
4x = -8
x = -2
Linear function.
14). 4x - 3 + 2y = 8x - 9
4x + 2y - 3 - 4x = 8x - 4x - 9
2y - 3 = 4x - 9
2y = 4x - 9 + 3
2y = 4x - 6
y = 2x - 3
Linear function.
