Answer:
First number is -2.5
Second number 5
Step-by-step explanation:
Four times the first number minus three times the second number is 2.
To represent this statement, 4x -3y =2
Two times the first number increased by three times the second is 10.
To represent thsi statement, 2x+ 3y = 10
4x - 3y = 2
2x + 3y =10
4x - 2x = 2x
2x = -5
x= -2.5
The first number is -2.5
By using Substitution
2x + 3y = 10
2(-2.5) + 3y = 10
-5 + 3y = 10
3y = 10 +5
3y =15
y = 5
The second number is 5
....To check my answer
-5 + 15 = 10

so whatever is square rooted must be equal to 1
1 squared is 1
-2+3 is one

155 is the answer
-3 × -5 = -15
-15 × 0 = 0
3/5 is 12/20 simplified. :)
1. Find the greatest common factor of 12 and 20 which is 4.
2. Divide 12 by 4 and 20 by 4.
3. 12/4=3 and 20/4=5
4. 3/5!
