Answer 2

1)B=2,A=1,C=5 то есть :1+2=3 2+5=7 7+3=10
2)A=2,B=3,C=5 то есть : 2+3=5 2+5=7 7+5=12
3)B=3,C=2,A=1 то есть : 3+2=5 1+2=3 5+3=8

Answer 3

Let's solve the given system of equations:

1. AB + BC = 10cm
2. AB + AC = 12cm
3. BC + AC = 8cm

To find the values of AB, BC, and AC, we can use a method called substitution. Let's start by solving for one variable in terms of the others.

From equation 1, we have: AB = 10cm - BC ...(4)

Now, substitute the value of AB from equation 4 into equation 2:

10cm - BC + AC = 12cm

Now, rearrange the equation to solve for AC:

AC = 12cm - 10cm + BC AC = 2cm + BC ...(5)

Now, substitute the value of AB from equation 4 into equation 3:

BC + 10cm - BC = 8cm

Now, rearrange the equation to solve for BC:

BC - BC = 8cm - 10cm 0 = -2cm

Since we ended up with 0 = -2cm, there must be an error in the original system of equations. It seems like there's an inconsistency in the given information.

Please double-check the values or equations provided to ensure accuracy, or provide additional information if there is anything missing.
