7(1 – y) = -3(y – 2) anyone know answer?
Favorite Answer
7-7y=-3y+6 (because a negative integer multiplied by a negative integer is a positive)
Now, lets group like terms:
7-7y+3y=-3y+6+3y which becomes 7-4y=6
and 7-4y-7=6-7 which becomes -4y=-1
Since both sides of the equation have one term, and both terms are negative, we can remove the negatives and work with positives. This gives us 4y=1. Lastly, lets isolate y by dividing giving us
y=1/4
Lastly, you’ll want to substitute 1/4 into the original equation for all the y’s and double check it’s right.
Step 1: Multiply by distribution.
7-7y= -3y-6
Step 2: Move constants to one side and variables to the opposite side.
7-7y=-3y-6
(7-7)-7y+3y=(-3y+3y)-6-7
-7y+3y=-6-7
Step 3: Simplify
-7y+3y=-6-7
-4y=1
Step 4: Solve for y
-4y/-4 =1/-4
Answer: y= 1/-4 or -0.25
7=4y + 6
1=4y
y= 1/4
-7……………-7
-7y= -3y-1
+3y…+3y
-4y=-1
/-4…./-4
y=1/4
