Find the value of 5x+3 given that -3x-7=5

-17

Step-by-step explanation:

First, we want to solve for x in -3x-7=5.

-3x-7=5  Add 7 on both sides.

   +7 +7

-3x=12   Divide by -3 on both sides.

/-3  /-3

x=-4      

Since we have the answer for this equation, we have to substitute x with -4 in 5x+3.

5(-4)+3  Using the order of operations, we multiply before adding.

-20+3    5(-4)=-20...now we can add.

=-17

Hop this helped!! Have a nice day C:

y=1/4x-4

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
