Answer:
x=2 y=2
Step-by-step explanation:
Second: x=3 y=1.5
Answer:
yes we should >:(
Step-by-step explanation:
Eay peasy
solve graphically
graph them and find the poitn that they intersect at
y=mx+b
m=slope
b= y intercept
y=7x-9
slope=7
yintercept=-9
y=3x-1
slope=3
yinercept=-1
I have attached graph below
easier way would be to simply sub them and solve
7x-9=y=3x-1
7x-9=3x-1
4x-9=-1
4x=8
x=2
y=3x-1
y=3*2-1
y=6-1
y=5
(2,5) is solution
