When subtracting integers:
1) Change subtraction to addition
2) If second number is negative change to positive or if second number is positive change to negative.
3)solve as if it were addition
ONLY USE FOR SUBTRACTION
4- -2 would change to 4+2
Your answer is 6.
4
2y = 4 (divide both sides by 2 to solve) y = 2
((3+4)x2+4)-2
the answer is 4
2-4; 2-4; 2-4; 2-4; 4-4
-2
10
2-4; 2-4; 2-4; 2-4; 4-4
126
3x - 4 = -2 The answer is x=2/3
4 over 1 is 4. 2 + 4 is 6.
say it is 1 over 2 is equal to x over 4 you multiply 4 and 1 then 2 and x and you get 4=2x. Solve for x = 2. So the equivalent proportion is 2/4.
