50t=500(8.5)
t=10(8.5)
t=85 minutes
you first use distributive property for the multiplication
[(2*4x)-(2*11)]+9=19
8x-22+9=19
Then, you need to leave the variable alone moving all the other numbers with the opposite operation (addition to substraction, substraction to addition, multiplication to division, division to multiplication)
8x=19+22-9
8x=(19+22)-9
8x=41-9
8x=32
Then as 8 and x are multiplying you pass it dividing
x=32/8
x=4
6x3+8x2-2x+4=30-2x
10x3+x2+11x+9=21+13x
Its 2.456*10=11
