solve each linear equation..
y=x+4
y=-2x+1
I just need help on one of them.
you can't "solve" a linear equation. It just describes a function.
Now, if you want to see where the two functions are the same, you need
x+4 = -2x+1
3x = 3
x = 1
so, y=5
If you want to find the root, where y=0, then just set y=0 and solve for x:
0 = x+4
x = -4
As you said, that you can't solve a linear equation, that's what it says in the textbook.. also I've checked the back of the book and it says the coordinates are (-1,3). Sorry for the bother.
I am sure Steve meant to type
3x = -3
thus x = -1 and therefore y = 3
just like your textbook said
Of course! Let's solve the first linear equation, which is:
y = x + 4
To solve for x, we need to isolate x on one side of the equation. Here's how you can do it step by step:
Step 1: Start with the equation: y = x + 4
Step 2: Subtract 4 from both sides to isolate x:
y - 4 = x
That's it! Now you have solved the equation. The solution is x = y - 4, which means that the value of x can be any value of y minus 4.
