Question is in picture, the middle one, apologies for the others cropping into it.

c. (6,1)

Step-by-step explanation:

Add both x and both y (11+1)=12 (5+-3)=2 then divide both by 2

(6,1)

answer: it's d

step-by-step explanation:

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
