Solve for x. Thanks!

Vladimir79 [104]

Answer:

x = $\frac{2T}{nd}$ - a

Step-by-step explanation:

Multiply both sides by 2 to eliminate the fraction

2T = n(a + x)d

Since n and d are both multipliers, divide both sides by nd

$\frac{2T}{nd}$ = a + x

Isolate x by subtracting a from both sides, hence

x = $\frac{2T}{nd}$ - a
