Question

Which operations would create an equivalent system of equations with opposite like terms?
3x-3y = 3
4x+ 5y = 13
The first equation can be multiplied by 5 and the second equation by 3.
The first equation can be multiplied by -4 and the second equation by -3.
The first equation can be multiplied by 4 and the second equation by -4.
The first equation can be multiplied by 3 and the second equation by 5.

Answer 1

The first equation can be multiplied by 5 and the second equation by 3.

3x - 3y = 3 | × 5

4x + 5y = 13 | × 3

15x - 15y = 15

12x + 15y = 39  +

________________

15x + 12x - 15y + 15y = 15 + 39

27x = 54

x = 54 : 27

x = 2

4·2 + 5y = 13

5y = 13 - 8

5y = 5

y = 5 ; 5

y = 1
