Use the substitution method to solve the system of equations. {y=3x−715x−5y=14 what is the solution? the solution is (15, 5). the solution is (0, 7). there is no solution. there are an infinite number of solutions.

Using the substitution method to solve the system of equations there is no solution.

The two equations are known as simultaneous equations:

y=3x−7 equation 1

15x−5y=14 equation 2

In order to solve for the above equations, substitute for y in equation 2

15x - 5(3x - 7) = 14

15x - 15x + 35 = 14

15x - 15x = 14 - 35

= -21.

There is no solution

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
