If the point (a,3) lies on the graph of the equation 5x + y = 8, then a=

Dear Kyle,

Sub (a,3) into the equation 5x + y = 8
5a + 3 = 8
5a = 5
a = 1
Hope it helps!
wishing you the best of luck,
Barry

To find the value of a, we can substitute the coordinates of the given point (a,3) into the equation 5x + y = 8 and solve for a.

Step 1: Substitute the values of x and y into the equation.
5(a) + 3 = 8

Step 2: Simplify the equation by multiplying.
5a + 3 = 8

Step 3: Solve for a by isolating the variable a.
Subtract 3 from both sides of the equation:
5a + 3 - 3 = 8 - 3
5a = 5

Step 4: Divide both sides of the equation by 5 to solve for a.
5a/5 = 5/5
a = 1

Therefore, if the point (a,3) lies on the graph of the equation 5x + y = 8, then the value of a is 1.

To find the value of 'a' when the point (a, 3) lies on the graph of the equation 5x + y = 8, we need to substitute the given values into the equation and solve for 'a'.

Substituting the value of 'x' as 'a' and the value of 'y' as '3', we get:

5(a) + (3) = 8

Simplifying the equation further:

5a + 3 = 8

Next, subtract 3 from both sides of the equation to isolate the term with 'a':

5a + 3 - 3 = 8 - 3

This simplifies to:

5a = 5

Finally, divide both sides of the equation by 5 to solve for 'a':

5a/5 = 5/5

The equation becomes:

a = 1

Therefore, when the point (a, 3) lies on the graph of the equation 5x + y = 8, 'a' is equal to 1.
