-3x > 0
Divide both sides by -3 remembering to "flip" the inequality as you do so, because it's negative.
Answer: 12y + 11
Step-by-step explanation:
12 x y + 11
Add the two equations to get -y=-1. So, y=1. Solving for x, you get that x=5.
So the solution is (5,1)

➷ Writing it out like this will help:
7 : 3 : 2
? : 3.75 : ?
So, 3.75 is 3 parts as per this ratio
Divide this amount by 3 to get 1 part in the ratio
3.75 / 3 = 1.25
Now simply multiply all the other ratios by this value to find how much the others get:
1.25 x 7 = 8.75
1.25 x 2 = 2.5
Paula gets £8.75 and Henry gets £2.50
The amount altogether would be their individual amounts added together:
8.75 + 2.50 + 3.75 = 15
The total amount of money is £15.
