Which is not an equation of the line going through (3,-6) and (1,2)? y+6=-4(x-3)
y-2=-4(x-1)
y-1=-4(x-2)
y=-4x+6

x = 10

Step-by-step explanation:

1. 4x-20+6x+5 = 85

2. 10x-15 = 85

3. 10x = 100

4. x = 10

Step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
