Given: 2√(x + 2) - 3 = 7 Add three to both sides: 2√(x + 2) = 10 Divide both sides by two: √(x + 2) = 5 Square both sides: x + 2 = 25 Subtract two from both sides: x = 23
Multiply the entire expression by a least common multiple and then simplify the expression. In this case, the least common multiple is 30 so multiply the entire expression by 30 and simplify.
To solve this expression for x: (2x - 3) / (√x + 2) = √x We'll first multiply both sides by the denominator on the left: 2x - 3 = x + 2√x Then subtract x from both sides: x - 3 = 2√x Move all...
