Answer:

The value of the provide equation is y=\frac{-1+2x}{6}\ or\ y=\frac{2x-1}{6}.

Step-by-step explanation:

Consider the provided equation.

7=14x-42y

We need to solve the equation for y.

Subtract 14x from both sides.

7-14x=14x-14x-42y

7-14x=-42y

Divide both the sides by -42.

\frac{7-14x}{-42}=\frac{-42y}{-42}

\frac{1-2x}{-6}=y

\frac{-1+2x}{6}=y

y=\frac{-1+2x}{6}

Hence, the value of the provide equation is y=\frac{-1+2x}{6}\ or\ y=\frac{2x-1}{6}.

7 = 14x - 42y
42y = 14x - 7
y = (14x - 7)/ 42

or we could write it as  y = (1/3)x - 1/6

alisha [4.7K]
Let the larger number be w and the smaller number be k;
5w-11=3k
3k+16=4w
Reorganizing the equations;
5w-3k=11
4w-3k=16
Subtracting equation 2 from equation 1:
w=-5
Replacing value of w in equation 1;
5(-5)-11=3k
-25-11=3k
3k=-36
k=-12
The numbers are -5 and -12
