Simplifying -3 + a = 7x(2xa + -1) Reorder the terms: -3 + a = 7x(-1 + 2ax) -3 + a = (-1 * 7x + 2ax * 7x) Reorder the terms: -3 + a = (14ax2 + -7x) -3 + a = (14ax2 + -7x) Solving -3 + a = 14ax2 + -7x Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-14ax2' to each side of the equation. -3 + a + -14ax2 = 14ax2 + -14ax2 + -7x Combine like terms: 14ax2 + -14ax2 = 0 -3 + a + -14ax2 = 0 + -7x -3 + a + -14ax2 = -7x Add '3' to each side of the equation. -3 + a + 3 + -14ax2 = 3 + -7x Reorder the terms: -3 + 3 + a + -14ax2 = 3 + -7x Combine like terms: -3 + 3 = 0 0 + a + -14ax2 = 3 + -7x a + -14ax2 = 3 + -7x Reorder the terms: -3 + a + -14ax2 + 7x = 3 + -7x + -3 + 7x Reorder the terms: -3 + a + -14ax2 + 7x = 3 + -3 + -7x + 7x Combine like terms: 3 + -3 = 0 -3 + a + -14ax2 + 7x = 0 + -7x + 7x -3 + a + -14ax2 + 7x = -7x + 7x Combine like terms: -7x + 7x = 0 -3 + a + -14ax2 + 7x = 0 The solution to this equation could not be determined.
