Question

How can x + 3 = −2x + 5 be set up as a system of equations?

Answer 1

Answer:

y = x + 3 and y = -2x + 5

Step-by-step explanation:

If we consider one set of equation as:

$y = x + 3$

and the other set of equation as:

$y = - 2 x + 5$

Since the left hand side for both these equations is same, therefore we can equate the right hand side and write it as:

$x + 3 = - 2 x + 5$

Answer 2

Answer:

y  = x+3;  y = -2x +5

Step-by-step explanation:

x + 3 = -2x + 5

Let   y = x + 3 = -2x + 5

If a = b = c then a=b and a=c

we can write the equation as

y = x + 3 and y = -2x + 5

Thus, this is the system of equations

y = x + 3

y = -2x + 5
