Answer:

False , there is one solution

Explanation:

given the system of equations

3x + 5y = 20 → (1)

- 2x + 5y = 20 → (2)

subtract (2) from (1) term by term

3x - (- 2x) + (5y - 5y = 20 - 20

3x + 2x + 0 = 0

5x = 0 ⇒ x = 0

substitute x = 0 into either of the 2 equations and solve for y

substituting into (1)

3(0) + 5y = 20

0 + 5y = 20

5y = 20 ( divide both sides by 5 )

y = 4

solution is (0, 4 )
