Well, 417 + 417 + 417 +417 is the same as 4 x 417, because you are adding 417 together 4 times. So, the equation can be rewritten as 4 x 417 = 4x. From here, you should divide both sides by 4. This will get x by itself, giving you the value of x. If you didn't plug 4x 417 into a calculator yet, you can see that when you divide it by 4, the 4s cancel and you are left with 417. Thus, x = 417
2y = 4x + 4y = 2x + 2
x= -.5
16x+9 without the rest of the equation, what this equals, I can't solve
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
4x = 72.divide both sides by 4x = 18
2y = 4x + 4y = 2x + 2
many solutions
x= -.5
You can't solve it. But you can simplify it to get: 4x+y=2
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
Add 4x - 2 to each side: 5x = 5 x = 1
You cannot solve one linear equation with two variables.
8+4x
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
16
4x+7-3x = 15 4x-3x = 15-7 x = 8
