Solve the following please

a) 25

b) 14

Step-by-step explanation:

Subtract 3 on both sides.

a/5 + 3 - 3 = 8 - 3

a/5 = 5

Multiply 5 on both sides.

a/5(5) = 5(5)

a = 25

Add 1 on both sides.

(3b)/7- 1 + 1 = 5 + 1

(3b)/7 = 6

Multiply both sides by 7.

(3b)/7 (7) = 6(7)

3b = 42

Divide both sides by 3.

(3b)/3 = 42/3

b = 14

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
