Question

What is the solution of the system? 7x+5y=19 and -7x-2y=-16 Need help ASAP

Answer 1

Answer:

x = 2, y = 1

Step-by-step explanation:

• 7x + 5y = 19
• -7x - 2y = -16

Use the elimination method to solve the system of equations. Add the terms from top to bottom. 7x and -7x cancel out.

0 + 3y = 3

Divide both sides by 3.

y = 1

Substitute 1 for y into the first equation.

7x + 5(1) = 19

7x + 5 = 19

Subtract 5 from both sides.

7x = 14

Divide both sides by 7.

x = 2
