Solve this system of equations by substitution: −3x + 3y = 3 and −5x + y = 13

x = -5  y = 12

Step-by-step explanation:

-3x + 3y = 3

-5x + y = 13

y = 13 +5x

-3x + (13+5x) = 3

x = -5

-5(-5) + y = 13

y= 12

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
