How to use it?
- Express {x} in terms of y where:
- 18*x+19*y=7
- 8*x-13*y=-12
- 1*x+6*y=6
- -6*x+1*y=-5
- Equation:
-
Equation x^2-9=(x+3)^2
-
Equation x+12=5
-
Equation 1-x/2=x/3
-
Equation x^2+x=12
-
Identical expressions
- nine *x- nineteen *y= two
- 9 multiply by x minus 19 multiply by y equally 2
- nine multiply by x minus nineteen multiply by y equally two
- 9x-19y=2
-
Similar expressions
- 9*x+19*y=2

The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 19 y + 2$$
Divide both parts of the equation by 9
We get the answer: x = 2/9 + 19*y/9
9*x-19*y = 2
Looking for similar summands in the left part:
-19*y + 9*x = 2
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 19 y + 2$$
Divide both parts of the equation by 9
x = 2 + 19*y / (9)
We get the answer: x = 2/9 + 19*y/9
