Q. Solve the following equation for w.5−4w=w+8w=
Given equation: We are given the equation:5−4w=w+8To solve for w, we need to isolate w on one side of the equation. The first step is to remove the square roots by squaring both sides of the equation.
Step 1: Remove square roots: Square both sides of the equation:(5−4w)2=(w+8)2This simplifies to:5−4w=w+8
Step 2: Simplify the equation: Now, we need to get all the w terms on one side and the constant terms on the other side. Let's move the w terms to the left side and the constants to the right side by adding 4w to both sides and subtracting 8 from both sides:5−4w+4w=w+8+4w−8This simplifies to:5=w+4w
Step 3: Rearrange the equation: To combine the w terms, we need a common denominator. The common denominator is 4, so we rewrite w as 44w:5=44w+4wThis simplifies to:5=4(4w+w)
Step 4: Combine like terms: Now, multiply both sides by 4 to get rid of the denominator:4×5=(4w+w)This simplifies to:20=5w
Step 5: Multiply both sides: Finally, divide both sides by 5 to solve for w:520=55wThis simplifies to:4=w
