Answer:last one
Step-by-step explanation:
x= -13 , y=11
Step-by-step explanation:
Using elimination method, make the x variable equal to eliminate the variable
-3x - y = -28
2x+ 3y=7
2(-3x-y =28)
3(2x+3y=7)
-6x - 2y =56
6x +9y=21
Apply addition
7y = 77
y=77/7 = 11
Use the value of y=11 in
2x+ 3y=7
2x +3(11) =7
2x +33 =7
2x=7-33
2x= -26
x= -26/2 = -13

Answer:
- No solution for x, when k = 1
- x = 68/(k - 1), when k≠ 1
Step-by-step explanation:
<u>Given the equation</u>
- kx – 17 = 51 + x, where k = 1,
<u>Solve for x:</u>
- 1*x - 17 = 51 + x
- x - 17 = x + 51
- x - x = 51 + 17
- 0 = 68,
Incorrect equation, no solution for x when k=1
<u>Solving for x when k ≠ 1</u>
- kx - 17 = 51 + x
- kx - x = 51 + 17
- x(k - 1) = 68
- x = 68/(k - 1)
