Question

solve using substitution.
y = 7
8x - 7y = -1
(□, □)
submit

Explanation:

Step1: Substitute \( y = 7 \) into the second equation

We have the equation \( 8x - 7y=-1 \), substitute \( y = 7 \) into it:
\( 8x-7\times7=-1 \)

Step2: Simplify and solve for \( x \)

First, calculate \( 7\times7 = 49 \), so the equation becomes:
\( 8x - 49=-1 \)
Add 49 to both sides:
\( 8x=-1 + 49 \)
\( 8x = 48 \)
Divide both sides by 8:
\( x=\frac{48}{8}=6 \)

Answer:

\((6, 7)\)
