Although all of the following systems can be solved via the substitution method, the substitution would be the best method for solving which system?

y = 3x + 1

y = 3x - 5

y = 2x + 3

2x + y = 5

0.5t - w = 2.5

2t + 3w = 4

3x + 2y = 18

4x + 5y = 60

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

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
