True,
The problem is 2x+6=90
Using the equation and substituting x for 42
You use PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
In this equation you substitute like I said above
So the equation should look like
2(42)+6=90
You use PEMDAS but since there are no parentheses or exponents you skip to multiplication. So 2×42 is
- Then you continue with what is left so now you have 84+6=90
84 plus 6 is 90
So the answer is TRUE.
I hope this was helpful :)
Goodluck!
