Answer:
-7
Step-by-step explanation:
first multiply 3 and 4 because PEMDAS
so it now looks like
12 - 9 - x = 10
now minus 12 and 9
3 - x = 10
move x to the other side by adding x to both sides
3 = 10 + x
and move 10 to the other side by subtracting 10 to both sides
3 - 10 = x
x = -7
now check
3*4 - 9 - (-7) = 10 ?
12 - 9 + 7 = 10 ?
3 + 7 = 10 ?
10 = 10
First answer is 3 do all the parentheses first
