Answer:
-146, but I could be wrong, so wait till someone else answers
Step-by-step explanation:
3x-12=60°
3x-12+(12)=60+(12)
3x=72
3x÷(3)=60÷(3)
x=24
Answer:
the right one's are
1,2,5,6
Step-by-step explanation : I hope this helps everyone
Step-by-step explanation:
you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.
if yes, it was a solution, and if just only one is false, then it was not a solution.
(3, -2) in
y + 4x = 10
5x - y = 13
so,
-2 + 4×3 = 10
-2 + 12 = 10
10 = 10 true
5×3 - (-2) = 13
15 + 2 = 13
17 = 13 false
so, it was NOT a solution.
