Question

Solve the following equation. Then determine if the equation is an identity or a contradiction.

3(2 - 3x) = -7x - 2(x - 3)

Answer 1

.3(2 - 3x) = -7x - 2(x - 3)

6-9x=-7x-2x+6

6-9x=-9x+6

we solve :

6-9x+9x-6=0

0x=0

whatever the value of "x", the equation is always true (0 equals 0). it is an identity.

3(2 - 3x) = -7x - 2(x - 3) is an identity, because it is true for all values ​​of x
