Suppose the following system of equations has a solution of (9,-5)), where A, B, C, D, E, and F are real numbers Ax + By =C
Dx + Ey =F

Which systems are also guaranteed to have a solution of (9,-5)? Select all that apply.

.

answer: options

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
