A system of equations has no solution if y=8x+7 is one of the equations, which could be the other equation?

Translated to english from person who answered before

Step-by-step explanation:

A system of equations is a set of equations with the same unknowns. A

Linear equation system is a system of equations in which each equation is linear. A solution of a system is a mapping of values for unknowns that makes

true each of the equations. Solving a system means finding all the solutions in the system.

Here's an example of a system of linear equations with two unknowns:

Equation 1

Equation 2 b

2x and 5

x 4 and 7

We can check that x 3 and y 1 is a solution of this system.

Equation 1 Equation 2

2132 1 5 3 4112 7

2x and 5 x 4y 7

529 and 531

step-by-step explanation:

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
