For challenge a million the first step is to combine like words by including and subtracting from both aspect. 5x -2x = 13 -a million Now upload those 3x = 12 now divide by 3 to get x by itself x = 4 As for challenge 2 commence off a similar way 7x - 2x = 8 + 2 combine the words 5x = 10 Now divide by 5 to get x by itself x = 2

1- 3x -7y = 2x+8 is linear
it is x-7y -8 =0
2- 2x-8 = y^ 2 is not linear

A linear equation is one where all terms are to the first power.
If we solve both of these for y, we see that we still have the form x^1; whereas in the second we have x^(1/2).
So the first equation is the linear equation.

3x-7y=2x+8 is the linear equation
2006-12-29 11:37:05 · answer #5 · answered by Anonymous · 1⤊ 0⤋
3x - 7y = 2x + 8
-7y = -x + 8
y = (1/7)x - (8/7) or (x - 8)/7
since this is in the form of y = mx + b, this one is linear.
2x - 8 = y^2
y = sqrt(2x - 8)
This problem isn't linear.

I assume you mean linear. Equations which result in a graph that is a straight line is called linear. Equations that have exponents equal to 1 and do not have terms like X*Y are linear.
Equation 1 is linear.
Equation 2 is not linear.

The first one, because all the variables appear
to the first power only. In the second one,
the y is squared and that makes it nonlinear.
By the way, "liner" should be spelled "linear".

Just the first one, the second one I think would be parabola:
-7y=-x+8
y=1/7x-8/7

1. 2 is not since y^2 term.
