5/8 * 4/5
= 1/8 * 4/1
= 1/4 * 2/1
1/2 * 1/1
Final answer = 1/2
Simplify brackets
351 = y * 8 + 7
Regroup terms
351 = 8y + 7
Subtract 7 from both sides
351 - 7 = 8y
Simplify 351 - 7 to 344
344 = 8y
Divide both sides by 8
344/8 = y
Simplify 344/8 to 43
43 = y
Switch sides
<u>y = 43</u>
17/20 is the answer
