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 }}
