To solve inequalities is the same as solving equations, except that, when you divide the sign reverses.
☆Open the brackets first
( -5 ×3x ) + ( -5 × 4 ) = -15x -20
☆ Collect like terms
-15x -20 < 6 -3x
-15x + 3x < 6 + 20 (Change the sign)
-12x > 26 (Divide by -12 ,change the sign)
x < 26 ÷ -12
x < -2. 17 (3sf)
