2x + 5 - 8x + 12 + 3 (x - 4) after distributing and collecting like terms thos problem simplified is -7x + 5 true or false
( explain i dont get this stuff)

0 is its x and y coordinate

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
