Ineed the result step by step: 18+6[26-7(1+2])

Step-by-step explanation:

To use order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) the numbers from left to right. Please Excuse My Dear Aunt Sally!

First, solve parenthesis.

Next, multiply numbers from left to right.

Then, add numbers from left to right.

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
