Question

Now, evaluate the expression on the right side of the equation to find the value of y.
y= 4x−5
x= −6y+20
x = 2

y
=
4x−5

y
=
4 · 2 − 5

y
=

Answer 1

To find the value of \( y \) using the expression \( y = 4x - 5 \) and substituting \( x = 2 \):

1. Start with the equation:
\[
y = 4x - 5
\]

2. Substitute \( x = 2 \) into the equation:
\[
y = 4 \cdot 2 - 5
\]

3. Calculate \( 4 \cdot 2 \):
\[
4 \cdot 2 = 8
\]

4. Now substitute this back into the equation:
\[
y = 8 - 5
\]

5. Finally, calculate \( 8 - 5 \):
\[
y = 3
\]

So, the value of \( y \) is \( \boxed{3} \).
