Answer:
2.6Kg
Step-by-step explanation:
Let the weight of apples be x and that of pears be y .
The farmer sold 7.1 kg of apples and pears .
4.5 of the 7.1kg is apples
That’s
x + y = 7.1kg
4.5kg + y = 7.1kg
Subtract 4.5kg from both sides
4.5kg - 4.5kg + y = 7.1kg - 4.5kg
y = 2.6 kg
The farmer sold 2.6kg of pears at the market

k-(7) =k-7 upon 7 k- (k-7)upon 7 =0 k upon 4 -(k-7)=0
Answer:
5x + y = 26
Step-by-step explanation:
Step 1: Distribute
y - 1 = -5x + 25
Step 2: Add 1 to both sides
y = -5x + 26
Step 3: Move 5 to the other side
5x + y = 26
I'm assuminng you want to find x and y
eliminate
hmm
eliminate y's
3 times 2=6
multiply first equation by 2 and 2nd by 3 and add
16x-6y=-32
<u>15x+6y=-123 +</u>
31x+0y=155
31x=155
divide both sides by 31
x=5
sub back
5x+2y=-41
5(5)+2y=-41
25+2y=-41
minus 25 both sides
2y=-66
divide by 2
y=-33
(x,y)
(5,-33)
Domain is X
Range is Y
Therefore {-3,-1,1}
Remember you don’t repeat numbers if there is more than one
