Answer:
Step-by-step explanation:
y=x+7.........(1)
y=3x+5.......(2)
Equating the two equations
3x +5 = x + 7
3x -x = 7 - 5
2x = 2
x = 2/2
x = 1
Putting x = 1 in (1)
y = x + 7
y = 1 + 7
y = 8

I don't know sorry I ain't smart
Answer:
A(1,1)
Step-by-step explanation:
the system is :
2x-y=1
x+2y=3
so :
y = 2x-1 .....the line color : red
y= (-1/2)x+3/2......the line color : blue
the pair solution is the intersection point for this line : A(1 ; 1)

Answer:
x=-3,x1/2
Step-by-step explanation:
f(x)=(2x-1)(x+3)
TI find x intercept/zero substitute
f(x)=0
0=(2x-1)x(x+3)
swap the sides of the equation
(2x-1)x(x+3)=0
when the product of factors equals 0,at least one factor is zero
2x-1=0
x+3=0
solve the equation for x
x=1/2
x+3=0
solve the equation of x
x=-3
The equation has two solution
x=-3
x=1/2
