Solve for x: 7x + 3 = 45

x = 6

Step-by-step explanation: To solve for x in the equation you see here, our goal is to get x by itself so we will use inverse operations.

Inverse operations is a technique used to solve equations. It's the same thing as order of operations but it's done in the reverse order.

We can see that we have multiplication and addition going

on in this equation so if we are following inverse

operations, we want to undo addition.

So I am going to use the subtraction property of equality on both sides.

That leaves us with 7x = 42.

Now to undo multiplication, I am going to use the division property of equality and that's used to to get our variable alone.

Dividing both sides by 7, we find that x = 6.

hope this helps....

answer: hey there,

the answer you are looking for is a..

hope this you!

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
