Question

Solving by substitution- Day 1
solve the following system of equations y=9x-9 y=9

Answer 1

(x, y) = (2, 9)

Explanation:

y = 9x - 9

y = 9

Substituting the value of y ( second equation) into the first eqaution, we get:

9 = 9x - 9

18 = 9x

x = 2.

Answer 2

(x, y) = (2, 9)

Explanation:

y = 9x - 9

y = 9

Substituting the value of y ( second equation) into the first eqaution, we get:

9 = 9x - 9

18 = 9x

x = 2.
