Answer:
The value of s is "90". A further explanation is given below.
Step-by-step explanation:
The given expression is:
⇒ 10=s÷2+7
i.e,
⇒ 
On solving the above expression, we get
⇒ 
On applying cross-multiplication, we get
⇒ 
⇒ 
6x - 2 = -4x + 2
Spencer: 6x - 2 = -4x + 2 /+4x6x - 2 + 4x = -4x + 2 + 4x10x - 2 = 2
Jeremiah:6x - 2 = -4x + 2 /-6x6x - 2 - 6x = -4x + 2 - 6x-2 = -10x + 2
They both are correct. But in Jeremiah's version of solving the equation, we would have to multiply equation by -1, which we don't have to do in the Spencer's version.

Answer:
v=18
Step-by-step explanation:
26=8+v
<em>Swap sides:</em>
8+v=26
<em>Subtract 8 from both sides:</em>
8+v-8=26-8
<em>Group like terms:</em>
v+8-8=26-8
<em>Simplify the arithmetic:</em>
v=26-8
v=18
