Use back-substitution to solve the system of linear equations.
ludmilkaskok [199]

Step-by-step explanation:

x - y + 5z = 29

y + 2z = 4

z = 7

since z = 7 we can use this value in second equation

y + 2×7 = 4 and y = -10

now we know the value of y we can solve the first equation

x -(-10) + 5×7 = 29

x + 10 + 35 = 29

x = -11

2y-3x=7

2) slope 1/5, y-intercept 3

5y-x=15

3) slope 1/5, y-intercept 4/5

-x+5y=4

4) slope 5/2, y-intercept 7/2

2y=5x+7

Step by step explanation:

1) 2y-3x=7

2y=3x+7

y=3/2y+7/2

2)5y-x=15

5y=x+15

y=1/5x+3

3)-x+5y=4

5y=x+4

y=1/5x+4/5

4)2y=5x+7

y=5/2x+7/2
