Complete Question

Solve for b.

2/3b + 5 = 20 - b

b = 9

Step-by-step explanation:

We are given the algebraic expression

2/3b + 5 = 20 - b

Step 1

Collect like terms

2/3b + b = 20 - 5

Step 2

Solve for the left hand side of the equation

2/3b + b = 15

(5/3)b = 15

Step 3

Cross multiply

5b = 15 × 3

Step 4

Divide both sides by 5

5b/5 = 45/5

b = 9

)=(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.
