Question 1097804: When calculating his income tax an accountant realized that his federal tax was 30% of his income after his provincial tax was paid, and that his provincial tax was 20% of his income after his federal tax was paid. If the accountant's income before taxes amounted to $47 000, how much federal tax did he have to pay?

his income is 47000.
his federal tax is 30% of (47000 minus his provincial tax).
his provincial tax is 20% of (47000 minus his federal tax).
let F equal his federal tax.
let P equal his provincial tax.
your equations are:
F = .3 * (47000 - P)
P = .2 * (47000 - F)
simplify these equations to get:
F = 14100 - .3P
P = 9400 - .2F
you have two equations that need to be solved simultaneously.
add .3 * P to both sides of the first equation and add .2 * F to both sides of the second equation to get:
F + .3P = 14100
.2F + P = 9400
leave the first equation as is and multiply both sides of the second equation by 5 to get:
F + .3P = 14100
F + 5P = 47000
subtract the first equation from the second to get:
4.7P = 32900
solve for P to get P = 32900 / 4.7 = 7000.
go back to your first original equation and solve for F to get:
F = .3 * (47000 - P) becomes F = .3 * (47000 - 7000)) which becomes F = .3 * 40000 which becomes F = 12000.
his federal tax is 12,000.
his provincial tax is 7,000.
