Sally invests $5000. She puts one part in an account with 7% interest, and the rest in an account with 8.5% interest for three years. If the total interest she earns is $1,176, how many dollars did she put on the first account?

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
