Question

3. Find the solution of the equation from the values of the variable given in the brackets
a. 7m = 21 (1, 2, 3, 4)
b. y - 11 = 9 (20,19,9, 11)
c. 3x + 1 = 7 (0, 2, 3, - 1)
d. 5x - 7 = 3 (1,-1,- 2,2)
e. Z + 1 = 0 (0, 1, 2, - 1)
f. 3p + 6 = 0 (2,- 2,3, - 3)​

Answer 1

Answer:

a. 3

b. y=20

c. x=2

d. x=2

e. z=-1

f. p=-2

Step-by-step explanation:

a. 7m=21

m=21/7

m=3

b. y-11=9

y=9+11

y=20

c. 3x+1=7

3x=7-1

3x=6

x=6/3

x=2

d. 5x-7=3

5x=7+3

5x=10

x=10/5

x=2

e. z+1=0

z=-1

f. 3p+6=0

3p=-6

p=-6/3

p=-2

Answer 2

Answer:

3x+1=7(0,2,3,-1

Step-by-step explanation:

putx=0

3×0=7.0=7
