Answer:
x = 7/10
Step-by-step explanation:
9/5 x -2/5 = (8x+3)/10
get a common denominator of 10
9/5 x * 2/2 - 2/5 * 2/2 = (8x+3)/10
18 /10 x - 4/10 = (8x+3)/10
multiply by 10 on each side to clear the fractions
10 *(18 /10 x - 4/10) = 10*(8x+3)/10
distribute
10 *(18 /10 x) -10* 4/10) = 10*(8x+3)/10
18x - 4 = 8x+3
subtract 8x from each side
18x-8x -4 = 8x+3 -8x
10x-4 = 3
add 4 to each side
10x-4+4 = 3+4
10x = 7
divide by 10
10x/10 = 7/10
x = 7/10
