Two is thirty-one, divided by the sum of a number and four. find the number.

a. 11.5
b. –15.5
c. 13.5
d. none of the above

2 is 31 didivded by the sum of a number and 4
translate
2 (2) is (=) 31 divded by (31/) the sum of a number and 4 (x+4)
2=31/(x+4)
times both sides by x+4
2(x+4)=31
divide both sides by 2
x+4=15.5
minus 4 from both sides
x=11.5
