Answer:
Incorrect.
Step-by-step explanation:
6 + x = 19
Plug in when x = 12
6 + 12 = 19
18 = 19
It is incorrect, so 12 is not a solution.
It is not a solution
Substitute into the equation and see if it is true
6+12 = 19
18 =19
This is not true so it is not a solution
58 yds (squared yards) 6 × 7 = 42, 4 × 4 = 16; 42 + 16 = 58
hope this helps!
x = 45
5 (2x - 5) = 1/2 (18x + 40)
10x - 25 = 9x + 20
10x = 9x + 45
27
30/2=15 +12=27
