3x + -1y = 12
Solving
3x + -1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
3x + -1y + y = 12 + y
Combine like terms: -1y + y = 0
3x + 0 = 12 + y
3x = 12 + y
Divide each side by '3'.
x = 4 + 0.3333333333y
Simplifying
x = 4 + 0.3333333333y</span>

Answer
Our two equations are:
+=16(1)
=55(2)
Rewriting equation (1) in terms of just = something, we get:
=16−
Substituting this into equation (2) leaves us:
(16−)=55
16−2=55⟹=5 or 11
which can be easily seen by factoring or using the quadratic formula. It follows that =11|=5 and =5|=11.
Thus your solutions in terms of (,) are (5,11) and (11,5).
Step-by-step explanation:
What is the digit at the hundred thousands place? It is 2. Is the digit to the right of it less than 5? No, 5 is 5. So replace the digits to the right of 2 with 0, and change the 2 to 3.
