Question

Solve the equation
-2(7-y)+4=-4

Answer 1

• 
  `\bf y = 3`

Explanation:

`\sf -2(7-y)+4=-4`

Let's start by distributing the -2 to the terms inside the parentheses:-

• 
  `\sf -2* 7=-14`

• 
  `\sf -2* y=2y`

→

• 
  `\sf -14 +2y+4=-4`

Now, let's combine like terms:-

• 
  `\sf -10+2y=-4`

Add 10 to both sides:-

• 
  `\sf -10+2y+10=-4+10`

• 
  `\sf 2y=6`

Divide both sides by 2:-

• 
  `\sf 2y/2=6/2`

• 
  `\sf y=3`

Therefore, the solution to the equation -2(7-y)+4=-4 is y = 3.

Answer 2

The solution to the equation is y = 3.

Explanation:

Given equation:

`\sf -2(7 - y) + 4 = -4`

Distribute the -2 on the left side:

`\sf -14 + 2y + 4 = -4`

Combine like terms:

`\sf 2y - 10 = -4`

Isolate the variable y by adding 10 to both sides:

`\sf 2y-10+10 = -4 +10`

`\sf 2y = 6`

Solve for y by dividing both sides by 2:

`\sf y=(6)/(2)`

`\sf y = 3`

So, the solution to the equation is y = 3.
