Create an equation with a solution closest to 0 using digits 1 to 9

_x + _ = _x + _

Answer:

See Explanation

Step-by-step explanation:

Given

_x + _ = _x + _

Required

Fill in the gap using 1 to 9 to give a result close to 0

First, you have to determine what kind of numbers that are close to 0;

In this case, I'll work with -0.4 to 0.4 because the number in this range approximate to 0;

Next, is to fill in the gaps using trial by error method

5x + 2 = 2x + 3

Checking the above expression

$5x - 2x = 3 - 2$

$3x = 1$

Divide equation by 2

$x = 0.33$ (Approximated)

Another trial is

6x + 8 = 2x + 7

Checking the above expression

$6x - 2x = 7 - 8$

$4x = -1$

Divide equation by 4

$x = -0.25$ (Approximated)

I'll stop here but note that, there are more expressions that can fill in the gaps
