You would have to multiply the top and bottom of both fractions, to get equal number between them,
<span>Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same.</span>
Step-by-step explanation:
Let the number be X
3×X=3X
Increased by 2
3X+2>0≤-3
Shouldn't the equation read " (x - 4)² = 81 ", instead of "(1 - 4)² = 81" ?
If so, then the solutions are x = -5 and x = 13 .
If it's really "(1 - 4)² = 81", then that's not even an equation, and there's no solution.
