Answer:
22.6
Step-by-step explanation:
We are asked in the problem to determine the inverse of the relation y = 3x + 12. first step is to express the equation in terms of y, that is y -12 = 3x, then exchange the places of x and y, that is x - 12 = 3y. This is the final answer
C - 2c = 2c - 2c - 4
c - 2c = -4
-c = -4
c = 4
Decimal fractions don't exist. Do you mean convert to a decimal and a fraction?
(x+y=31)2
2x-y=11
2x+2y=62
- 2x -y=11
3y=51
y=17
x+17=31
x=14
y-x=3
