He has 151 pages left in his book

Step-by-step explanation:

Saturday

1 hr = 38 pg

3.5 x 38 = 133

Sunday

1 hr = 44 pg

3.5 x 44 = 154

pages read

133 + 154 = 287

starting amount 438

438 - 287 = 151

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
