find the solution to the system of equations.
−7x−2y=14

6x+6y=18

x=

y=

x = - 4, y = 7

Step-by-step explanation:

Given the 2 equations

-7x - 2y = 14 → (1)

6x + 6y = 18 → (2) ← Divide all terms by 6

x + y = 3 ← rearrange expressing x in terms of y, subtract y from both sides

x = 3 - y → (3)

Substitute x = 3 - y into (1)

- 7(3 - y) - 2y = 14

- 21 + 7y - 2y = 14

- 21 + 5y = 14 ( add 21 to both sides )

5y = 35 ( divide both sides by 5 )

y = 7

Substitute y = 7 into (3) for corresponding value of x

x = 3 - 7 = - 4

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
