Sam thinks of a number n. he multiplies his number by 7 and then he adds 3 to the result. his final answer is 45. write down an equation for this information solve the equation and find the number n.

N x 7 +3 = 45

N = 6    Hope this helps.

Hi GueenSilia,

(n x 7) + 3

45 - 3 = 42

42 / 7 = n

n x 7 + 3 = 45

42 / 7 = 6

6 x 7 = 42

42 + 3 = 45

n = 6

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
