How do you solve XY by elimination?
The Elimination Method
- Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.
- Step 2: Subtract the second equation from the first.
- Step 3: Solve this new equation for y.
- Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
How many solutions does X Y 7 have?
Answer: Any two solutions of the equation x + y = 7 are (1, 6) and (0, 7). Explanation: A linear equation is of the form ax + b = c. Geometrically, it represents a line.
Which is the linear equation in two variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
How do you solve 2xy?
Thus 2xy means 2 times x times y or said algebraically 2xy = 2 \times x \times y. If you want the operation between two symbols to be something else, like plus, you have to say it explicitly. Thus for x plus y you need to write x + y.
