Solve each system by substitution y=4x-5
y=2x-5
Need help with this asap and I need my work shown as well!!!

x = 0, y = -5

Step-by-step explanation:

you're given two equations:

y = 4x - 5

y = 2x - 5

to solve, just substitute y in the second equation.

y = 2x - 5

4x - 5 = 2x - 5

now that you have this, solve for x.

4x - 5 = 2x - 5

subtract 2x from both sides

4x - 5 - 2x = 2x - 5 - 2x

2x - 5 = -5

add 5 to both sides

2x - 5 + 5 = - 5 + 5

2x = 0

divide both sides by 2

2x/2 = 0/2

x = 0

now that you know x, substitute x for 0 in the second equation.

y = 2x - 5

y = 2 * 0 - 5

y = 0 - 5

y = - 5

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
