Given ; 2(10-13x)+9x=-34x+60
step 1 20-26x+9x- -34x+60
step 2 17x= - 34x +40
step 3 51x= 40
step 4 x= 40/51
in what step is there first an error. explain the error and how to correctly work the problem

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
