Solution:
<u>Step-1: Subtract 4.3 both sides.</u>
- x/5 + 4.3 = 12.4
- => x/5 + 4.3 - 4.3 = 12.4 - 4.3
- => x/5 = 8.1
<u>Step-2: Use cross multiplication to find x.</u>
- x/5 = 8.1
- => x = 8.1 x 5
- => x = 40.5
Hence, the value of x is 40.5.
6 x -9 = -54
<span>6 + (-9) = -3
</span>x2<span> - 3x - 54 = 0
</span>
<span>(X + 6 ) (X - 9)
</span>
x2<span> - 3x - 54 = (X + 6 ) (X - 9)
=
6 & -9
