Please, make sure you understand the solution:
We can notice that x + (x - 28) = 90
2x - 28 = 90
2x = 118
<u>x = 59</u>
<u />
Now for y:
We can notice that y + 90 + x = 180
y + 90 + 59 = 180
y + 149 = 180
y = 180 - 149
<u>y = 31</u>
Answer:
false
Step-by-step explanation:
This is a solution to the first equation because
5+-9=-4
-4=-4
however, if you plug it into the next equation, it becomes false.
5--9=4
14=4
this does not make sense.
K =80
40 x 2 = 80 so 80 \ 2 = 40
