Plug in x with -1

A negative number in parenthesis times an exponent is always positive.
8+3-7=4
Answer:
0.5
Step-by-step explanation:
8x+6=10
8x=10-6
8x=4
x=4/8=0.5
4(x-7)=12=
4x-28=12
add 28 to both sides
4x=40
x =40/4 = 10
x = 10
(-12) + 6/12 = 12/1 + 6/12=18/12=1 6/12 or 1/2
This is PEMDAS as well as order of operations and or parentheses, exponents, multiplication, division, addition, and subtraction. Multiplication and division go together, so you do whichever one comes first. Same goes to addition and subtraction. A way to remember the order is Please Excuse My Dear Aunt Sally.
