3x-4y=-5
-x+2y=3
Multiply the second by one:
3x-4y=-5
-2x+4y=6
Combine the equations:
x = 1
Substitute x and solve for y:
-2*1+4y=6
-2+4y=6
4y=8
y=2
Answer:
(1,2)
11t=120(12)
11t=1440
t=1440/11
However t is in hours and we want to know days so:
d=(1440/11)/24
d=1440/264
d=60/11
d=5 5/11 days
3x≤-6
x=-2
mark it on the x axis and then shade to the left
The mistake is in Step 1. The solver should have also squared when squaring the other side of the equation.
<h3>Correctly solving</h3>
Hello.
Have a beautiful and joyful day ahead.
