Solve 2x + 5y = −13 3x − 4y = −8
zlopas [31]
If you would like to solve 2x + 5y = -13 and 3x - 4y = -8, you can do this using the following steps:

2x + 5y = -13       /*4
3x - 4y = -8         /*5
_______________
8x + 20y = -52
15x - 20y = -40
_______________
8x + 15x + 20y - 20y = -52 - 40
23x = -92
x = -92 / 23
x = -4

<span>3x - 4y = -8 
</span>3 * (-4) - 4y = -8
-12 - 4y = -8
12 + 4y = 8
4y = 8 -12
4y = -4
y = -1

The correct result would be x = -4 and y = -1.

A taxi service charges a flat fee of $1.25 and $0.75 per mile. if henri has $14.00, which of the following shows the number of m
andrey2020 [161]
Option m = 17

y = total cost of the service
m = number of miles run

y = 1.25 + 0.75 m

Equal the cost to the amount available by Henri

14 = 1.25 + 0.75m

Solve for m

m = (14 - 1.25)/0.75 = 12.75 / 0.75 = 17  miles.
