Question

Y= 5-3x
y= -3x+4

solution or no solution

Answer 1

no solution

Explanation:

y = 5 - 3x → (1)

y = - 3x + 4 → (2)

substitute y = - 3x + 4 into (1)

- 3x + 4 = 5 - 3x ( subtract 4 from both sides )

- 3x = 1 - 3x ( add 3x to both sides )

0 = 1 ← not possible

this indicates the system has no solutions
