Final answer:

The solution to the equation 3x+8y=19 is x = 1 and y = 2.

Step-by-step explanation:

To solve the simultaneous equation 3x + 8y = 19, we can use the method of substitution.

First, solve one equation for one variable in terms of the other variable.

Let's solve the equation 3x + 8y = 19 for x:

3x = 19 - 8y

x = (19 - 8y) / 3

Now substitute this expression for x in the other equation:

4y = 8

Solving for y, we get:

y = 8 / 4

= 2

Substitute this value of y back into the expression for x:

x = (19 - 8(2)) / 3 = (19 - 16) / 3

= 3 / 3

= 1

Therefore, the solution to the simultaneous equation 3x + 8y = 19 is x = 1 and y = 2.
