Answer 1

25 decreased by thrice a number is 7. What is the number?

25 - 3*n = 7

decreased by = subtract (-)

thrice = 3 times (multiply(x))

number = n (unknown variable)

is = Equals to (=)

Solving two-step equations with inverse operations.

25 - 3*n = 7

-25 -25

0 - 3*n = -18

-3*n = -18

-3 -3

Ans. n = 6

Answer 2

25 – 3x = 7

25 – 25 – 3x = 7 – 25

-3x = -18

-3x /-3 =   -18/-3

X =6
