Answer:
32
Step-by-step explanation:
Step 1: Distribute. On the right side, you should get =2x-4
Step 2: Add all common bases. You should get 4x-5 on the left side
Step 3: Add on each side. For example, add five to each side of the equation. Your equation should look like this; 4x= 2x+1
Step 4: Subtract each x number by 2x. Your equation should be; 2x=1
Step 5: Divide each side by two. Your answer should be x=1/2 or x=0.5

4b + 22 = 5 (b + 4) - 1 (remove the parantheses)
4b + 22 = 5b + 20 - 1 (calculate)
4b + 22 = 5b + 19 (move the terms)
4b - 5b = 19 - 22 (collect like terms and calculate)
-b = -3 (change the signs)
<em>b = 3</em>
Answer:
x = 20
Step-by-step explanation:
The 3 angles lie on a straight line and sum to 180° , that is
3x + 80 + 2x = 180
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
