Create an equation with a solution closest to 0 using digits 1 to 9
steposvetlana [31]

Complete Questions:

<em>Create an equation with a solution closest to 0 using digits 1 to 9 </em>

<em>_x + _ = _x + _</em>

<em></em>

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

<em>Collect Like Terms</em>

<em></em>5x - 2x = 3 - 2<em></em>

3x = 1

Divide equation by 2

x = 0.33 <em>(Approximated)</em>

Another trial is

6x + 8 = 2x + 7

Checking the above expression

<em>Collect Like Terms</em>

<em></em>6x - 2x = 7 - 8<em></em>

4x = -1

Divide equation by 4

x = -0.25 <em>(Approximated)</em>

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

Vsevolod [243]

Answer:

\displaystyle x=\frac{7\pm\sqrt{37}}{6}

Step-by-step explanation:

\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-(-7)\pm\sqrt{(-7)^2-4(3)(1)}}{2(3)}\\\\x=\frac{7\pm\sqrt{49-12}}{6}\\ \\x=\frac{7\pm\sqrt{37}}{6}

2.) a+ (-b)

a+(-b) -> 2+(-3)

=-1

3.) 3a (12-2b)

3a(12-2b) -> 3(2) (12-2x3)

6(12-6)

6(6)

=36

4.) 2a-c/b

2a-c/b -> 2(2)-5/3

4-5/3

=1/3
