Question

2(5x+4)=10x+6 is this equation sometimes always or never true?

Answer 1

Simplifying
2(5x + -4) = 10x + 6

Reorder the terms:
2(-4 + 5x) = 10x + 6
(-4 * 2 + 5x * 2) = 10x + 6
(-8 + 10x) = 10x + 6

Reorder the terms:
-8 + 10x = 6 + 10x

Add '-10x' to each side of the equation.
-8 + 10x + -10x = 6 + 10x + -10x

Combine like terms: 10x + -10x = 0
-8 + 0 = 6 + 10x + -10x
-8 = 6 + 10x + -10x

Combine like terms: 10x + -10x = 0
-8 = 6 + 0
-8 = 6

Solving
-8 = 6

Answer 2

This equation is invalid, the left and right sides are not equal, therefore there is no solution.
