Question

5y-11=3y+9
3x + 4 = 7 – 2x
9 – 2(y – 5) = y + 10
5(x – 1) = 3(2x – 5) – (1 – 3x)
2(y – 1) – 6y = 10 – 2(y – 4)
y/3 – (y – 2)/2 = 7/3
(y – 3)/4 + (y – 1)/5 – (y – 2)/3 = 1
(3x – 2)/3 + (2x + 3)/3 = (x + 7)/6
(8y – 5)/(7y + 1) = -4/5
(5 – 7y)/(2 + 4y) = -8/7. Solve these linear equations..​

Answer 1

Answer:

1. 5y-11=3y+9

5y-3y=9+11

2y=20

y=10

2.3x+4=7-2x

3x+2x=7-4

5x=3

X=3/5

3.9-2(y-5)=y+10

9-2y+10=y+10

-2y-y=10-9-10

-3y=-9

y=3

4.5(x-1)=3(2x-5)-(1-3x)

5x-5=6x-15-1+3x

5x-6x-3x=-15-1+5

-4x=-11

X=11/4

5.2(y – 1) – 6y = 10 – 2(y – 4)

2y-2-6y=10-2y+8

2y-6y+2y=10+8+2

-6y=20

y=10/3

6.y/3 – (y – 2)/2 = 7/3

y/3-y+2/2=7/3

(2y-3y+6)/6=7/3

-y+6=14

y=-8
