12 X +13 Y is equal to 140 FX is equal to 4 what is the value of Y

Answer: $Y =$ $\frac{92}{13}$

Step-by-step solution

We are given the equation $12X + 13Y = 140$ and the value of $X = 4$ . To find the value of $Y$ , we substitute $X = 4$ into the equation.

Next, we multiply $12$ by $4$ to simplify the equation. This gives us $48 +$ $13Y = 140$ .

To isolate the term with $Y$ , we subtract $48$ from both sides of the equation. This moves the constant term to the right side.

Now, we perform the subtraction on the right side of the equation: $140 - 48 = 92$ . So, the equation becomes $13Y = 92$ .

Finally, to solve for $Y$ , we divide both sides of the equation by $13$ . This gives us the value of Y.
