Question

0.2x+0.3y=1.3solve using substuting method plz fast I will make u brainlist and follow u​

Answer 1

Answer:

Step-by-step explanation:

Let's solve for x.

0.2x+0.3y=1.3

Step 1: Add -0.3y to both sides.

0.2x+0.3y+−0.3y=1.3+−0.3y

                         0.2x= -0.3y+1.3

Step 2: Step 2: Divide both sides by 0.2.

0.2x/0.2= -0.3y+1.3/0.2

           x= -1.5y+6.5

Let's solve for y  

Step 1: Add -0.2x to both sides.

0.2x+0.3y+−0.2x=1.3+−0.2x

0.3y=−0.2x+1.3

Step 2: Divide both sides by 0.3  

0.3y/0.3= -0.2x+1.3/0.3

           y=−0.666667x+4.333333

Note: We only use substitution method in systems of linear equations. If I am not wrong, I am pretty sure your teacher asked you covert this to y=mx+b form. Just in case I was wrong, I also put the solution for x.
