keep scrolling it is kind of long
Step-by-step explanation:
−2x+2y=−4,3x−2y=4
−2x+2y=−4for x:
−2x+2y=−4
−2x+2y+−2y=−4+−2y
−2x=−2y−4
-2x/-2=-2y-4/-2
x=y+2
Substitute y +2 for x in3x−2y=4:
3x−2y=4
3(y+2)−2y=4
y+6=4
y+6+−6=4+−6
y=−2
Substitute −2 for y in x=y+2:
x=y+2
x=−2+2
x=0
x=0 and y=−2
What you do is 28,140 - 5% cause when you are doing a type of problem like this (trying to fins what was the last year) that means to subtract cause she now has 28,140 , and that was from a 5% raise but what she is trying to figure out is that how much did she have before the raise , so we are gong to grab the increased salary (28,140) with the raise percentage that made it increase (5%) , now you subtract , 28,140 - 5% = 26,733 .. I subtracted and found my answer :)
your answer is 26,733 hope this helps :)
