Hope you liked my answer and it helped you

**Step-by-step explanation:**

Let x = the number of ounces of Solution A

Let y = the number of ounces of Solution B

x + y = 180 y = 180 - x

.60x + .85y = .75(180)

.60x + .85y = 135 Multiply both sides of the equation by 100 to remove the decimal points.

60x + 85y = 13500

60x + 85(180 - x) = 13500

60x + 15300 - 85x = 13500

-25x = -1800

x = 72ounces

y = 180 - 72

y = 108 ounces

6x + 7y = 59...multiply by -4

4x + 5y = 41...multiply by 6
