Question

7. Solve the following equations.
a.2(y + 4) = 16
b. -9=3(k+2)
c 3b/2-7=5
d 0=15+5 k(k-6)
8 a Construct two equations starting with x = 7 as solution.
b. Construct three equations starting with x = -5 as solution.​

Answer 1

Explanation:

a) 2y+8=16

2y=16-8

y=8/2

=4

b)3k+6=-9

3k=-9-6

k=-15/3

=-5

c)3b/2=7+5

3b=12.2

b=24/3

=8

Answer 2

Answer:

4

Explanation:

2(y+4)=16

2y+8=16

2y=16-8

2y=8

y=8/2

y=4
