Question
If Joe invested $7000 at x% and $13,000 at 3% more, find x if the income from both investments is $1190
I'm thinking that the equation would r something like 1,190=(13,000)(.03) but please correct me if I'm wrong. Thank you for your assistance.

no, your equation doesn't even contain any variables.
x(7000) + (x+.03)(13000) = 1190
7000x + 13000x + 390 = 1190
20000x = 800
x = .04 or 4%
x(7000) + (x+.03)(13000) = 1190
7000x + 13000x + 390 = 1190
20000x = 800
x = .04 or 4%
