I hope this is good enough:
Answer:
x=4
Step-by-step explanation:
The answer is (-2, 10) because when reflecting over the x, change the sign of y. When reflecting over the y, change the sign of x.
Answer:
38
Step-by-step explanation:
times 3x5 then add 18+20
13x - 6y = 2......multiply by 2
3x - 4y = -10....multiply by -3
------------------
26x - 12y = 4 (result of multiplying by 2)
-9x + 12y = 30 (result of multiplying by -3)
-----------------add
17x = 34
x = 34/17
x = 2
now sub 2 in for x into either of the original equations to find y
3x - 4y = -10
3(2) - 4y = -10
6 - 4y = -10
6 + 10 = 4y
16 = 4y
16/4 = y
4 = y
solution is (2,4)
