Answer:

19

Step-by-step explanation:

Let's solve for x:

[tex]2x+7y=−5[/tex]

Step 1: Add -7y to both sides.

[tex]2x+7y+−7y=−5+−7y \\ 2x=−7y−5[/tex]

Step 2: Divide both sides by 2.

[tex] \frac{2x}{2} = \frac{7y−5}{2}\\ x= \frac{ - 7}{2} y+ \frac{ - 5}{2}[/tex]

Therefore, the answer for the first one will be x = -7/2 y + -5/2.

Let's solve for x.

[tex]5x−7y=14[/tex]

Step 1: Add 7y to both sides.

[tex]5x−7y+7y=14+7y \\5x=7y+14[/tex]

Step 2: Divide both sides by 5.

[tex] \frac{5x}{5} = \frac{7y + 14}{5} \\ x= \frac{7}{5} y+ \frac{14}{5} [/tex]

Therefore, the answer for the second one will be x = 7/5 y + 14/5
