Tap to isolate

To solve by substitution, we first need an equation where one variable is by itself. Tap the expression that y is equal to.

Drag to substitute

Since we know what y equals, replace the y in the second equation with its package.

y

Slide to balance

We simplified the equation to .
Find the value of x that balances the scale!

{{ (prob.c + prob.m) * s3Slider + prob.b }}
{{ prob.e }}
{{ prob.e }}
x = 0 x = {{ s3Slider }} x = {{ maxSliderValue }}
Balanced! x = {{ prob.x }}

Build to find y

Now we know x = {{ prob.x }}. Go back to the first equation and build the value of y.

{{ prob.x }}
y =
{{ s4Value }}
Solution found: ({{prob.x}}, {{prob.y}})

System Solved!

Original System:

Solution:

x = {{ prob.x }}, y = {{ prob.y }}
