3r - 8 = 7 + 8r (make rs on 1 side, numbers on other)
5r = -15(divide by 5 now)
r = -3 (<---Answer)
Hope this helped!
5×7-13=22
which
5 times b-13=22
We have that
y=-2x+3
y=(1/3)x-4
using a graph tool
see the attached figure
the solution of the system is the point (3,-3)
Answer:
x = 3
Step-by-step explanation:
5x - 8 + 8 = 7 + 8
5x = 15
5x/5 = 15/5
15 divided by 5 equals 3
Hope this helped you out :)
