Consider the following system.
y = 4x - 1
y = -3x + 6
Find the solution by using substitution.

x = 1  y = 3

Step-by-step explanation:

4x - 1 = -3x + 6          Substitute the first equation for y in the second equation

+3x       + 3x              Add 3x to both sides

7x - 1 = 6

    + 1   +1                   Add 1 to both sides

7x = 7                         Divide both sides by 7

x = 1

Now plug this into the first equation

y = 4(1) - 1                   Multiply

y = 4 - 1                      Subtract

y = 3

step-by-step explanation:

$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.
