Just subisute values that will work
one easy way is to make one sides equal to only one of the placeholders, like y, and then lug in values in for x exg
x+2y=3
subtract x from both sides
2y=3-x
divideb bith sides by 2
y=-1/2x+3
subsitute valudes for x and get values for y
if x=2 then
y=-1/2(2)+3
y==-1+3
y=2
when x=2, y=2
when y=0 then y=3

2^4-8x2/4 (PEMDAS) Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
first you want to do exponents.. so 2x2x2x2 = 16
then you want to do multiplication so.. -8x2 = -16
now you have.. 16-16/4 .. then you want to do division so divide -16 by 4 and get -4
then you're left with 16-4 which is 12
THE ANSWER IS 12
Answer:
-24
Step-by-step explanation:
All you really have to do is multiply -6 by 4, and that results in -24. Remember, if there is only one negative sign, it will be negative, but if zero or two negative signs are present, the answer will be positive.
