Solve for x.

5/8(x+1/2)=100

3 answers

To solve for x, we can start by multiplying both sides of the equation by the reciprocal of 5/8, which is 8/5:

(8/5) * (5/8)(x + 1/2) = (8/5) * 100

Simplifying, we have:

(x + 1/2) = (8/5) * 100

Next, we can multiply both sides of the equation by 2 to eliminate the fraction on the left side:

2(x + 1/2) = 2 * (8/5) * 100

Simplifying further:

2x + 1 = 16/5 * 100
2x + 1 = 16 * 20
2x + 1 = 320

Now, we can subtract 1 from both sides of the equation to isolate 2x:

2x = 320 - 1
2x = 319

Finally, divide both sides of the equation by 2 to solve for x:

x = 319/2

Thus, x = 159.5.

Apologies for the error in the previous response. Let's solve the equation correctly:

To solve for x, we'll start by multiplying both sides of the equation by the reciprocal of 5/8, which is 8/5:

(8/5) * (5/8)(x + 1/2) = (8/5) * 100

Simplifying, we have:

Next, let's multiply both sides by 2 to eliminate the fraction on the left side:

2(x + 1/2) = 2 * (8/5) * 100

Simplifying further:

2x + 1 = 8/5 * 100
2x + 1 = 8 * 20
2x + 1 = 160

Now, let's subtract 1 from both sides to isolate 2x:

2x = 160 - 1
2x = 159

Finally, divide both sides by 2 to solve for x:

x = 159/2
x = 79.5

Therefore, the solution to the equation is x = 79.5.
