Answer:
(-1,1)
Step-by-step explanation:
5x+2y= -2, x= -1/3 - 2/3y
5( -1/3 - 2/3y) +3y= -2
y= 1
x= -1/3 - 2/3 × 1
x= -1
14x45=630
43×2=86
(14×45)-(43×2)= 630-86=544
there would be 544 pens left
By any chance will it be (1,1)
Answer:
(d + 3) would be 10
Step-by-step explanation:
<u>Step 1: Distribute</u>
