Y = 3x -1 2x + 4y = 24
SOMEONE EXPLAIN IN STEPS PLEASE!!!

(2, 5 )

Step-by-step explanation:

Given the 2 equations

y = 3x - 1 → (1)

2x + 4y = 24 → (2)

Substitute y = 3x - 1 into (2)

2x + 4(3x - 1) = 24 ← distribute and simplify left side

2x + 12x - 4 = 24

14x - 4 = 24 ( add 4 to both sides )

14x = 28 ( divide both sides by 14 )

x = 2

Substitute x = 2 into (1) for corresponding value of y

y = 3(2) - 1 = 6 - 1 = 5

solution is (2, 5 )

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
