The substitution method should be used to solve which **system** **of** **equations**? answer choices . 5x-7y=16 2x-7y=12. 4x+3y=-5 6x-3y=2. Question: Question Find the general **solution** **of** **the** following **system** **of** **equations**. - 4x - y 12x + **3y** 7 --21 Select the correct answer below: O (2,4x + 7) O (7,43 - 11) O(,-43-7) O ( FEEDBACK This problem has been solved!. Consider a normal **equation** in x such as: 3x = 6. To solve this **equation** you simply take the 3 in front of x and put it, dividing, below the 6 on the right side of the equal sign. x = 6 3 = 3β1 β
6 = 2. at this point you can "read" the **solution** as: x = 2. With a **system** **of** n **equations** in n unknowns you do basically the same, the only.

Built-in command-line test runner which runs the <b>tests</b> either sequentially or in. Classify each **system of equations** as having a single **solution**, no **solution**, or infinite **solutions**. 8.2 Graphical **Solution**. Consider the **system** of two linear **equations** in two variables x and y. (1) a1 x+b1 y+c1=0 ( a1 , b1 not both 0) a2 x+b2 y+c2=0 ( a2, b2 not both 0) Since the graph of each equation is a straight line we have the following three. Then substitute the result for that variable in the other **equation**. 2x+3y=2,x-2y=8. 2 x + **3** **y** = 2, x β 2 y = 8. Choose one of the **equations** and solve it for x by isolating x on the left hand side of the equal sign. Choose one of the **equations** and solve it for x by isolating x on the left hand side of the equal sign. For the linear **equations** given below, write another linear **equation** in two variables, such that the geometrical representation of the pair so formed **is**. (**i**) Intersecting lines (ii) Parallel lines (iii) Coincident lines. (a) 2x - **3y** = 6 (b) y = 2x + 3. 4. Find the value of k for which the given **system** **of** **equations** has a unique **solution**.
