y=3x-7y=3x−7y, equals, 3, x, minus, 7 Complete the missing value in the solution to the equation. (1,(1,left parenthesis, 1, comma ))

20335+282=20617

step-by-step explanation:

2nd one in the first row is correct

translate k to n and reflect across the line containing jk.

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
