Answer:
-9 = b
Step-by-step explanation:
-12=24+4b
subtract 24 from both sides
-36 = 4b
divide both sides by 4 to get variable by itself
-9 = b
Let's find X. Since both equations are equal to y, they are equal to themselves.
-3x-3=-3; we just need to solve from here. -3x-3=-3; let's add 3 to both sides. -3x=0; this means that 0 is X.
Let's use a graph to check.
So, y is -3.
So, (0, -3) is when the two lines intersect and it's our solution.
Answer: k = 27
Step-by-step explanation:
Here's the complete question:
Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.
An increase in k simply means that there's an addition. This will be:
k + 7 = 34
k = 34 - 7
k = 27
Therefore, the value of k is 27
