Multiply 1/4 (4r -12) = r-2
r-3 = r-2
Subtract r from each side
-3= -2 this equation has no solution
Round up if the previous digit is 5 or above, leave it the same (only the hundreth digit, erase all the other thousandths and such) if it is 4 or below
I can’t help but you did just help me get an answer correct
You can use a simultaneous equation - x + 7y=24 minus x-9y= -24 you end up with 16y = 48
Divide 48 by 16 and you get 3 is equal to y. Now put three into an equation eg, x + 21 = 24 it is now obvious that x = 3 as well as y = 3
Answer:
y = 6
Step-by-step explanation:
y = -4(1) + 10 = -4 + 10 = 6
