Question

linear equations.
1.Solve the equations.
a) 7x + 9 = - 40
b) ⅔ y - 8 = 12

c) 23 - y = 9

d) 6y + 15 = 12​

Answer 1

Answer:

a) -7

b)30

c)14

d)-3/6

Step-by-step explanation:

a) 7x + 9 = -40

=7x = -40 - 9

=7x = -40 - 9=7x = -49

=7x = -40 - 9=7x = -49=x = -49/7

=7x = -40 - 9=7x = -49=x = -49/7=x = -7

b) 2y - 8 = 12

3

=2y = 12 + 8

=2y = 12 + 8 3

=2y = 12 + 8 3=2y = 20

=2y = 12 + 8 3=2y = 20 3

=2y = 12 + 8 3=2y = 20 3=y = 20 × 3/2

=2y = 12 + 8 3=2y = 20 3=y = 20 × 3/2=y = 30

_________________________________

c) 23 - y = 9

= -y = 9 - 23

= -y = 9 - 23= -y = -14

= -y = 9 - 23= -y = -14=y = -(-14)

= -y = 9 - 23= -y = -14=y = -(-14)=y = 14

________________________________

d)6y + 15 = 12

=6y = 12 - 15

=6y = 12 - 15=6y = -3

=6y = 12 - 15=6y = -3=y = -36
