Can you help me please :))

Step-by-step explanation:

15x - 31 = 9x + 11

6x =42

x = 7

15(7) - 31 = 9(7) + 11

74 = 74

74 × 2 = 148

180-148=32

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

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
