Lin and priya were working on solving this system of equations.
{1/3x+2y=4
x+y=-3

lin's first move is to multiply the first  equation  by 3. 

priya's first move is to multiply the second  equation by 2.

explain why either move creates a new equation with the same solutions as the original equation.

the first equation is x + 6y = 36

the second equation is x+y = -6

(x, y) =(-6,3)

step-by-step explanation:

answer: 193

explanation:

200-7 = 193

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
