Solve the equation for x.
2x+5+12= -3

x=-10

Step-by-step explanation:

To solve the equation, isolate the variable. Do this by combining like terms and using the properties of equality. Remember that like terms are terms with the same degree and variables. Thus, constants are like terms.

First, combine the like terms of 5 and 12

Then, subtract 17 from both sides

Finally, divide both sides by 2

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
