Question

Solve the following for y: -6 +2y = 8

Answer 1

y = 7 is the answer.

Explanation:

We have given the equation:

-6 +2y = 8

We have to solve it for y.

So, we have given:

-6 +2y = 8

Adding 6 on both sides of the equation we get,

-6+6+2y = 8+6

2y = 14

Multiplying 1/2 on both sides of the equation we get,

y = 14/2

y= 7

y=7 is the solution of equation.

Answer 2

• y = 7

Explanation:

1) Given: - 6 + 2y = 8

2) Addition property of equalities: add 6 to both sides

• 2y = 8 + 6
• 2y = 14

3) Division property of equalities: divide by 2 both sides

• y = 14 / 2
• y = 7

4) Verify:

• -6 + 2y = 8
• - 6 + 2 (7) = 8 [substitution]
• - 6 + 14 = 8 [multiplication operation]
• 8 = 8 [addition operation]
• Conclusion: true
