To solve the system of equations
Answer to Problem 19SGR
Explanation of Solution
Given information:
Method used: Use elimination method to solve.
Calculation:
Let’s try to eliminate the y terms first.
Make coefficient of y terms as same but with different coefficients.
So, multiply the first equation by -2 and multiply second equation by 3.
Add the equations to eliminate the y terms.
Divide both sides by -2.
Substitute x as 3 into any of the given equations.
Add both sides 15.
Divide both sides by 3.
