Answer:
x = 2
y = 5
Explanation:
There are multiple ways to solve this system, but the method I used was substitution.
Substitution is basically when you plug in one equation into the other equation, then solve.
First off, you would plug y=x+3 into 3x+y=11.
So now your new equation would be 3x+(x+3)=11.
Then you solve for x.
1. Eliminate redundant parentheses. Now the equation is 3x+x+3=11.
2. Combine like terms. Since 3x + x = 4x, the equation is now 4x+3=11.
3. Subtract 3 from both sides of the equation. The new equation is 4x=8.
4. Divide both terms by 4. The answer is x=2.
Since you now know what x equals, plug in what x equals into the previous equation that included y.
So now your new equation is y=2+3.
1. Add the numbers. The answer is y = 5.
