Answer 1

For the first row (the left one), you just need to replace a for 8. If a=8 then a-3 turns into 8-3 and the answer is 5

Answer 2

Answer:

Step-by-step explanation: These were the ones i knew how to solve ;

$a - 3\\a = 8\\8-3 \\=5\\\\8(c-1)\\c = 5\\8(5-1)\\8(4)\\=32\\\\\frac{n+9}{6} \\n =15\\\frac{15+9}{6} \\\frac{24}{6} \\=4\\\\\frac{9p-13}{5} \\p=7\\\frac{9(7)-13}{5} \\=\frac{63-13}{5}\\=\frac{50}{5}\\=10\\\\4x-7\\x=7\\4(7)-7\\28-7\\=21$

I Hope it helps
