How do you solve 7y + 1 = 43

MakcuM [25]

Answer:

What we want is the answer on one side, and the variable on the other.

The first step in solving this is to get rid of the +1.

To do this we can use the inverse of operations, so we would subtract 1 from both sides.

7y +1 (-1) is 7y, ans 43-1 is 42.

Your problem now looks like

7y = 42

Next, we want to divide. We will divide both sides by 7

7y/7 is y, and 42/7 is 6.

Now our problem looks like

y = 6

6 is the answer

Hope it helps!

Write the equation of the line that passes through (–2, 1) and is perpendicular to the line 3x – 2y = 5.

dmitriy555 [2]

To make the perpendicular line, it is convenient to swap the x- and y-coefficients and negate one, then offset the x- and y- by the point value:
.. 2(x +2) +3(y -1) = 0

This equation can now be put into any desired form. Based on the given equation, it looks like you would like "standard form."
.. 2x +3y = -1
