Answer:
y=-9
Step-by-step explanation:
If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22
We can solve for multiplication first:
4-2y=22
Then we can subtract four on both sides, canceling out the four on the left side:
-2y=18
Now to isolate y, we divide both sides by -2, resulting in the solution:
y=-9
Hope this helps!
This statement is not true, you cannot add denominators if they are not the same
the correct answer is 8/15
brainliest answer please =)
(2/3) / -14 is the same as (2/3) * -(1/14) since we can multiply by the reciprocal when dividing with fractions.
2/3 * -1/14 = -2/42 = -1/21
