How do I solve 2x+3y=7, x-y=1

Fittoniya [83]

<span>2x+3y=7
x-y=1

</span>2x+3y=7
x=1+y

2*(1+y)+3y=7
x=1+y

2+2y+3y=7
x=1+y

5y=5 |(:5)
x=1+y

y=1
x=2

CHECK:
2x+3y=7
x-y=1

2*2 + 3*1 = 7

x-y = 1
2-1 = 1

We are to form the combination of 6 objects taken 2 at a time. This can be expressed as 6C2

$6C2= \frac{6!}{2!*4!} \\ \\ 
= \frac{6*5}{2} \\ \\ 
=15$

This means, there can be 15 different combinations of 2 members that can sit in the front row.

I’m really confused somebody please help

Answer: The mechanic worked for 4.25 hours for the fourth customer.

First find out the slope.
Y^2-y^1/x^2-x^1
210-90/3-1=60

Slope: 60

Then find out what the y-intercept is by plugging in values we know into y=mx+b

90=60(1)+b
30=b

Y=60x+30

Substitute the y with 285 to find out the x (hours)

285=60x+30
4.25=x
