Answer + Explanation:
149-12x+16 x=7
The x=7 means that the x in the equation 149-12x+16 would be substituted as 7.
149 minus 12 (x=7) +16
149 minus 12(7) plus 16
149 minus [12*7=63) plus 16
149 - 63 + 16
You would then do PEMDAS.
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
You will always solve the problem left to right, so it would be subtraction, first.
149-63= 86
Now you will add 86 and 16 which equals 102.
The answer is 102.
