Solve the equation 4- y = 9

y=-5

Step-by-step explanation:

4-y=9

Subtract 4 from both sides  

4-y-4=9-4

-y=5

Divide both sides by -1

-y/-1=5/-1

y=-5

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

ok
