Final answer:
To find the value of x from the expression 4x+6 = 34, subtract 6 from both sides to get 4x = 28, then divide by 4 to find x = 7. Substitute x into 2x+5 to get 2(7)+5, which equals 19.
Step-by-step explanation:
If the expression 4x+6 is equal to 34, we can find the value of x by solving the equation.
First, we isolate x by subtracting 6 from both sides of the equation.
This gives us 4x = 28.
Next, we divide both sides by 4 to get x = 7.
Now we want to find the value of 2x+5 for the same value of x.
Substitute x with 7 into the expression to get 2(7)+5, which simplifies to 14+5.
Therefore, 2x+5 equals 19 when x is 7.
