Answer:
5
Step-by-step explanation:
From the expression 2.8x + 6 > 20
we have,
2.8x + 6 = 20,
2.8x + 6 - (20) = 0 ( Moving all terms to the left)
We then add the numbers and variables together,
to get 2.8x + (6-20) = 0
2.8x + (-14) = 0
2.8x - 14 = 0
2.8x = 14 ( Divide both terms by 2.8x)
2.8x/2.8 = 14 /2.8
x = 14 / 2.8
x = 5
