This is system of equations and as such there are two methods of solving: elimination and substitution. Luckily Y is already isolated here, so in this case we just have to put in the value of y into 3x + 2y = 6

To do this we simply do:
3x + 2(-3/2+5) = 6
Distribute the 2 into the brackets
3x + -6/2 + 5 = 6
Move the 5 over and simplify the fraction
3x + (-3) = 1
Move the three over.
3x = 4
Isolate x
x=4/3

3D = 2T

Steve has 36 trios, that is, 36T. To find the equivalence to duos, we multiply the given relationship by 18:

18*3D = 18*2T

Operating:

54D = 36T

Therefore, 36 trios are equivalent to 54 duos.

Let x be the amount invested at 7% and y the amount invested at 6%


We know that the yearly interest earned = 0.07(x) and 0.06(y)

x+y =4500

0.07x +0.06 y =290

Solving the equations will give , x = $2,000 and y=$2,500
