Y=8
your teacher is introducing algebra
Answer:
x = 15
Step-by-step explanation:
7x. Try to ignore the X's for a second and think of the problem as -12+5 (aka 5-12). The answer to that is 7. now add the x back again to get: 7x
45 - 22 = 23
c + 22 = 45
23 + 22 = 45
I hoped this answered the question correctly! Have a great day!!:)
