Step-by-step explanation:

Let's solve for x.

2y+5x=4

Step 1: Add -2y to both sides.

5x+2y+−2y=4+−2y

5x=−2y+4

Step 2: Divide both sides by 5.

Write a complete two column proof for the following information.
andrey2020 [161]
We are asked to show a proof that m∠1 is equal to 62° and the line l is parallel to line m which has an angle of 180°. If two lines are parallel the summation of angles are 180 degrees and they are also considered as a supplementary angle. Hence, by this we have formed the equation and solution below:
m∠l + m∠m = 180° 
replacing the value of two angles, we have:
62° + 118° = 180°
180° = 180°

Therefore, the two lines are parallel.

eq. of line thro' two points is y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)=(0+3)/(4-0)=3/4

Reqd. eq . is y-(-3)=3/4(x-0)

or y=3/4(x)-3
