Find the value of x.

x = 16

Step-by-step explanation:

78 = 5x - 2

+ 2

80 = 5x

divide by 5

16 = x

Step-by-step explanation:

the value of 5x-2 should be 78° ( by vertically opposite angle)

so, after inserting values we got

5x - 2 = 78

→ 5x = 78 + 2 = 80

→ 5x = 80

→ x = 80/5 = 16

→ x = 16

therefore value of x is 16.

hope this answer helps you dear take care and hope u have great day ahead!

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
