WebOct 6, 2024 · Step 1: Simplify both sides of the equation using the order of operations and combine all same-side like terms. Step 2: Use the appropriate properties of equality to combine opposite-side like terms with the variable term on one side of the equation and the constant term on the other. Step 3: Divide or multiply as needed to isolate the variable. WebApr 16, 2024 · Exercise 2.3.19. Solve: 8n − 4 = − 2n + 6. Answer. Since 8 > − 2, make the left side the “variable” side. We don’t want variable terms on the right side—add 2n to both sides to leave only constants on the right. Combine like terms. We don’t want any constants on the left side, so add 4 to both sides. Simplify.
