Answer:

y = 14

Plug in 4 as x into the equation:

y = 2 + 3x

y = 2 + 3(4)

Simplify:

y = 2 + 12

y = 14

So, when x = 4, y = 14.

2b + 8 − 5b + 3 = -13 + 8b − 5<br><br><br><br> b = __
Bumek [7]

Answer:

b= 29/11

Step-by-step explanation:

2b+8−5b+3=−13+8b−5

Step 1: Simplify both sides of the equation.

2b+8−5b+3=−13+8b−5

2b+8+−5b+3=−13+8b+−5

(2b+−5b)+(8+3)=(8b)+(−13+−5)(Combine Like Terms)

−3b+11=8b+−18

−3b+11=8b−18

Step 2: Subtract 8b from both sides.

−3b+11−8b=8b−18−8b

−11b+11=−18

Step 3: Subtract 11 from both sides.

−11b+11−11=−18−11

−11b=−29

Step 4: Divide both sides by -11.

−11b/−11 = −29/−11

b= 29/11
