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

solution or no solution

no solution

Step-by-step 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

both equations and proportions are better.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
