Solve equation for x. Assume a=0.

Question

ax+3=23

Answer 1

On the other hand, if a ≠ 0, then ax = 20. So, x = 20/a.

Answer 2

Substitute 0 for a.

0x + 3 = 23

0 times any number = 0

0 + 3 = 23

3 = 23

No solution. No value of x makes this equation true.

Answer 3

If we assume a=0 and use it in the equation, the equation becomes 0.x+3=23

3=23

There is no solution when a=0 as x also becomes 0.

Answer 4

To solve the equation for x, we need to isolate x from the rest of the equation.

To do this first move 3 to the right side of the equation by subtracting it from both sides:

ax + 3 - 3 = 23 - 3

results in:

ax = 20

We're one step closer to having x by itself. Now we need to divide both sides by 'a'.

a/a = 1 Therefore:

ax/a = 20/a

Therefore: x = 20/a

If a is a non-zero number then x would be a real number. However, in this particular case since a=0, 20/0 is undefined, and therefore, this equation has no solution and x is undefined.

Answer 5

No solution.

a =0

0x+3=23

( every thing times 0 is 0 it self. Such as 0*10000=0)

0+3=23

3=23

(0 never equals 23)

thus no solution.
