Solving math problems can be fun and challenging!
Solving Systems by Substitution Check It Out! Example 1b Solve the system by substitution. x = 2y – 4 x + 8y = 16 Step 1 x = 2y – 4 The first equation is solved for x. Substitute 2y – 4 for x in
Step 1: Enter the system of equations you want to solve for by substitution. The solve by substitution calculator allows to find the solution to a system of two or three equations in both
The method of solving by substitution works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other

math is the study of numbers, shapes, and patterns. It is used in everyday life, from counting to measuring to more complex calculations.
Clarify math equations
One way to think about math equations is to think of them as a puzzle. Each piece of the equation fits together to create a complete picture. When one piece is missing, it can be difficult to see the whole picture.
From the second equation you get y = 3.25x + 14 and substitute into first equation. 2.5x – 3 (3.25x + 14) = – 13. 2.5x – 9.75x – 42 = – 13. – 7.25x = 29. x = -29/7.25 = – 4. Now
