Solve for linear equation by substitution
x + 4y = 6
y=-x+3

y=1 and x=2

Step-by-step explanation:

Substitute the y value in the first equation with the given equation for y. Now that all the terms are the same, you can solve for X by combining like terms.

ie: x+4(-x+3)=6

then

ie: x-4x+12=6

then

ie: -3x=-6

then divide -3 from each side and you'll end with x=2.

Now plug in your x value for the y equation.

ie: y=-2+3

And solve.

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
