Y=16x-7 и y=21x+8

To find the solution to the system of equations y = 16x -7 and y = 21x + 8, we can set the two equations equal to each other:

16x - 7 = 21x + 8

To solve for x, we need to isolate it on one side of the equation. Let's start by moving the terms with x to one side:

16x - 21x = 8 + 7

Simplifying the expression, we get:

-5x = 15

Now, divide both sides of the equation by -5:

(-5x) / -5 = 15 / -5

This simplifies to:

x = -3

Now that we have the value of x, we can substitute it back into one of the original equations to solve for y. Let's use the first equation:

y = 16(-3) - 7

Simplifying the expression, we get:

y = -48 - 7 y = -55

Therefore, the solution to the system of equations is x = -3 and y = -55.

Note: Please double-check your equations and calculations as there might be a mistake.
