Question 224068
The second given equation is already solved for {{{y}}}, so we can plug this equation into the first to obtain:
{{{3x+(x+3)=-5}}}. The second equation is simply put in the place of the {{{y}}} in the first equation.
To solve this, combine the {{{x}}} terms on the left hand side of the equation:
{{{4x+3=-5}}}.
Then, subtract the 3 from both sides:
{{{4x=-8}}}.
To obtain what {{{x}}} equals, divide both sides by 4:
{{{x=-2}}}.
This result can then be plugged back into the second equation to determine that {{{y}}} is equal to.
So:
{{{y=-2+3}}}
Which yields: {{{y=1}}}.
Our answer is then {{{x=-2}}}, {{{y=1}}}.
