Question

What does 149-12x +16 x=7 mean

Answer 1

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

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.
