For many people, math can be a difficult and challenging subject. However, with practice and perseverance, it is possible to improve one's math skills.
One way to think about math problems is to consider them as puzzles. To solve a math problem, you need to figure out what information you have.
Step 1: To solve a system of two equations in two variables graphically, we graph each equation. Step 2: To graph an equation manually, first convert it to the form \ (y=mx+b\)
Negative three times x, which now we're going to try out x being equal to negative three. Minus y, minus y. Y is positive three here. Minus y, gonna do that y color blue. Minus y now needs to be equal to, now needs to be equal, just like before

Solve for the other variable. You've found one variable, but you're not quite done yet. Plug your answer in to one of the original equations so you can solve for the other variable. For example: You know that x = 2, and one of your original equations is 3x - y = 3. Plug in 2 instead of x: 3(2) - y = 3. Solve for y in the equation: 6 - y = 3 See more
