Question

Solve for n in the equation: 2n -7 = -31. prove that your solution is correct.​

Answer 1

n = - 12

Explanation:

2n -7 = -31 ⇔ 2n = - 31 + 7 ⇔ 2n = - 24 ⇔ n = - 24/2 ⇔ n = -12

Proof : 2 × (-12) - 7 = - 24 - 7 = - 31

Answer 2

Answer: n=-12

Step-by-step explanation: (This question is basically isolating and combining things. If you have difficulties in these types of problems try checking out khan academy and the lesson expressions and equations in it.)

First, we need to add +7 on both sides of the equation to get 2n=-24 now all we have to do is divide 2 on both sides to get our answer n= -12!
