Question

Solving systems by

substitution: The "Blob" method
Finish solving the system. The first steps are
done for you. Write the answer in the form:
(x,y)-
2x + 3y = 7
y = 2x - 3
Steps:
2x + 3(2x - 3) = 7
2x + 6x – 9 = 7

Answer 1

(2, 1)

Explanation:

8x - 9 = 7

8x = 16

x = 2

y = 2(2) - 3

y = 4 - 3

y = 1
