solve for x

.08x + .05(x-1300) = 234

(I suggest multiplying each term by 100

would it be 23 or 2300

test your answer, but $23 wouldn't make a lot of sense, would it?

(did you multiply both sides by 100?)

from my equation :

.08x + .05(x-1300) = 234

times everybody by 100

8x + 5(x-1300) = 23400

8x + 5x - 6500 = 23400

13x = 29900

x = 2300

so larger amount = $2300

smaller investment = 1000

check:

.08(2300) + .05(1000) = 234
