0.5x-4/2.4+6=-5/3 equati
x=-20
Step-by-step explanation:
0.5x-4/2.4+6=-5/3
cross multiply
3(0.5x-4)=-5(2.4+6)
1.5x-12=-12+(-30)
1.5x=-42+12
1.5x=-30
x=-30÷1.5
x=-20
verification
substitute x value in equation
0.5(-20)-4/8.4=(-5)/3
-10-4/8.4= (-5) /3
-14/8.4=(-5)/3
-2.8×5/2.8×3=(-5) /3
cancel 2.8 in numerator and denominator then
(-5)/3=(-5)/3
hence x = (-20)
