Do this using the null … WebTo solve for x, we first. subtract 3 from both sides of the equation: 2x + 3 - 3 = 7 - 3. 2x = 4. Next, we divide both sides of the equation by 2: (2x)/2 = 4/2. x=2. So, the value of x that makes the equation true is 2. The Multiplication/Division Method involves first multiplying or dividing both sides.

Systems of Linear Equations: Solving by Addition / Elimination

WebSolve a system of linear equations by graphing. Step 1. Graph the first equation. Step 2. Graph the second equation on the same rectangular coordinate system. Step 3. Determine whether the lines intersect, are parallel, or are the same line. Step 4. Identify the solution to the system. If the lines intersect, identify the point of intersection. WebNow we have 1 equation and 1 unknown, we can solve this problem as the work below shows. The last step is to again use substitution, in this case we know that x = 1, but in order to find the y value of the solution, we just substitute x = 1 into either equation. hillcroft redhill
