Find the solution of the system of equations.
- 3x + 10y = 17
3x + 7y = 17

x=1, y=2. (1, 2).

Step-by-step explanation:

-3x+10y=17

3x+7y=17

17y=34

y=34/17

y=2

3x+7(2)=17

3x+14=17

3x=17-14

3x=3

x=3/3

x=1

Step-by-step explanation:

Given :

          equation 1

              equation 2

Adding the equation 1 and equation 2

Putting the value of 'y' in equation 2

So, the value are

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
