Answer:
d = 32
Explanation:
Given
+ 12 = 20 ( subtract 12 from both sides )
= 8 ( multiply both sides by 4 to clear the fraction )
d=32!!!
So first rewrite it as an equation: d/4+12=20
d/4+12=20 then subtract 12 from both sides to balance the equation
d/4=8 so multply both sides by 4 to isolate the variable, 4(d/4)=d =d and 8x4=32, so d=32
