How to solve a linear pair equation
WebExample 2: Solving simultaneous equations by elimination (subtraction) Solve: Eliminate one of the variables. By subtracting the two equations we can eliminate the variable b. NOTE: b − b = 0 so b is eliminated. 2 Find the value of one variable. 3 Find the value of the remaining variable/s via substitution. WebStep 1 : First, solve one linear equation for y in terms of x . Step 2 : Then substitute that expression for y in the other linear equation. You'll get an equation in x . Step 3 : Solve this, and you have the x -coordinate of the intersection. Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.

WebOct 10, 2024 · Solve the second equation for x by adding y to both sides: (x - y) + y = 1 + y. So x = 1 + y. Take that value of x, and substitute it into the first equation given above (x + y = 3). With that substitution the first equation becomes (1+y) + y = 3. That means 1 + 2y = 3. Subtract 1 from each side: 2y = 2. So y = 1. WebThese are all linear equations: Let us look more closely at one example: Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line When x increases, y increases …
