$y=5/4$

Solve:

$17=7+8y$

Switch sides.

$8y+7=17$

Subtract $7$ from both sides.

$8y+color(red)cancel(color(black)(7))-color(red)cancel(color(black)(7))=17-7$

Simplify.j

$8y=10$

Divide both sides by $8$ .

$(color(red)cancel(color(black)(8))^1y)/color(red)cancel(color(black)(8))^1=10/8$

Simplify.

$y=10/8$

Reduce by dividing the numerator and denominator by $2$ .

$y=(10-:2)/(8-:2)$

Simplify.

$y=5/4$
