learners sell 340 vetkoek for 15 weeks they charge R12 for each vetkoek calculate the profit they will make if the cost for each vetkoek is R4 and the costs of all ingredients is R623.48 per week​

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
