Solve for j in the proportion.

j=12

Step-by-step explanation:

1. Multiply 8 by both sides

8/1 x 3/2 = j/8 x 8/1

2. Solve

12=j or j=12

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
