How to use it?
- Express {x} in terms of y where:
- -15*x-2*y=19
- -19*x-6*y=10
- 19*x-6*y=0
- -3*x-10*y=-4
- Equation:
-
Equation sin(x)=0
-
Equation -2*(-2-y)-y-2=0
-
Equation 2*x^2+18*x=0
-
Equation sin(5*x)=-1
-
Identical expressions
- seven *x- eleven *y= four
- 7 multiply by x minus 11 multiply by y equally 4
- seven multiply by x minus eleven multiply by y equally four
- 7x-11y=4

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:
$$7 x = 11 y + 4$$
Divide both parts of the equation by 7
We get the answer: x = 4/7 + 11*y/7
7*x-11*y = 4
Looking for similar summands in the left part:
-11*y + 7*x = 4
Move the summands with the other variables
from left part to right part, we given:
$$7 x = 11 y + 4$$
Divide both parts of the equation by 7
x = 4 + 11*y / (7)
We get the answer: x = 4/7 + 11*y/7

$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{7} + \frac{11 i \operatorname{im}{\left(y\right)}}{7} + \frac{4}{7}$$
x1 = 11*re(y)/7 + 11*i*im(y)/7 + 4/7
