Q. Find the positive solution of the equation.2x76+28=156Answer:
Isolate x term: First, we need to isolate the term with the variable x on one side of the equation. To do this, we subtract 28 from both sides of the equation.2x(6/7)+28−28=156−28
Simplify right side: Now we simplify the right side of the equation by performing the subtraction.2x76=156−282x76=128
Divide by 2: Next, we divide both sides of the equation by 2 to solve for x76. 22x76=2128x76=64
Recognize power of 2: We recognize that 64 is a power of 2. Specifically, 64 is 2 raised to the 6th power (26). This will help us solve for x.x76=26
Raise to reciprocal: To solve for x, we need to raise both sides of the equation to the reciprocal of the fraction76, which is 67.(x76)67=(26)67
Multiply exponents: When we raise a power to a power, we multiply the exponents. In this case, (76)×(67)=1, so the left side simplifies to x. On the right side, we multiply the exponents: 6×(67)=7.x=27
Calculate value: Now we calculate 27 to find the value of x.27=128
