Answer:

Step-by-step explanation:

Given the 2 equations

4x + 8y = 21 → (1)

y = - $\frac{1}{2}$ x + 3 → (2)

Substitute y = - $\frac{1}{2}$ x + 3 into (1)

4x + 8(- $\frac{1}{2}$ x + 3 ) = 21 ← distribute parenthesis on left side

4x - 4x + 24 = 21 ( subtract 24 from both sides )

0 = - 3 ← not possible

This indicates the system has no solutions
