Simplifying (3a + 1) * x2 + (a + 2) + 1 = 7 Reorder the terms: (1 + 3a) * x2 + (a + 2) + 1 = 7 Reorder the terms for easier multiplication: x2(1 + 3a) + (a + 2) + 1 = 7 (1 * x2 + 3a * x2) + (a + 2) + 1 = 7 Reorder the terms: (3ax2 + 1x2) + (a + 2) + 1 = 7 (3ax2 + 1x2) + (a + 2) + 1 = 7 Reorder the terms: 3ax2 + 1x2 + (2 + a) + 1 = 7 Remove parenthesis around (2 + a) 3ax2 + 1x2 + 2 + a + 1 = 7 Reorder the terms: 2 + 1 + a + 3ax2 + 1x2 = 7 Combine like terms: 2 + 1 = 3 3 + a + 3ax2 + 1x2 = 7 Solving 3 + a + 3ax2 + 1x2 = 7 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + a + 3ax2 + -3 + 1x2 = 7 + -3 Reorder the terms: 3 + -3 + a + 3ax2 + 1x2 = 7 + -3 Combine like terms: 3 + -3 = 0 0 + a + 3ax2 + 1x2 = 7 + -3 a + 3ax2 + 1x2 = 7 + -3 Combine like terms: 7 + -3 = 4 a + 3ax2 + 1x2 = 4 Add '-1x2' to each side of the equation. a + 3ax2 + 1x2 + -1x2 = 4 + -1x2 Combine like terms: 1x2 + -1x2 = 0 a + 3ax2 + 0 = 4 + -1x2 a + 3ax2 = 4 + -1x2 Reorder the terms: -4 + a + 3ax2 + x2 = 4 + -1x2 + -4 + x2 Reorder the terms: -4 + a + 3ax2 + x2 = 4 + -4 + -1x2 + x2 Combine like terms: 4 + -4 = 0 -4 + a + 3ax2 + x2 = 0 + -1x2 + x2 -4 + a + 3ax2 + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 -4 + a + 3ax2 + x2 = 0 The solution to this equation could not be determined.
