Answer:
In standard form the first equation is 3x + 4y = 12
Step-by-step explanation:
In order to find this, we need to solve for the constant and then eliminate the denominators.
y = -3/4x + 3
3/4x + y = 3
3x + 4y = 12
Answer:
-19
Step-by-step explanation:
Answer:
b = 
Step-by-step explanation:
b +
= 1
← change to an improper fraction
b +
= 
Multiply through by 12 ( the LCM of 3 and 4 ) to clear the fractions
12b + 8 = 15 ( subtract 8 from both sides )
12b = 7 ( divide both sides by 12 )
b =
