Answer:9
Step-by-step explanation: the sequence move in odd numbers firstly from
-5 to -2 that is +3, -2 to 3 that is +5 and so on
64 - (3y + 8y + y) / 40 = 37
Simplify 3y + 8y + y
64 - 12y / 40 = 37
Add 12y / 40 to both sides and subtract 37
27 = 12y / 40
Multiply both sides by 40
1080 = 12y
Divide both sides by 12
90 = y
1) do the moltiplication
2) re arrange the equation
12 -12=24x
0=24x
so the first is impossible
