Solve the linear equations by using substitution -2x-5y=3 3x+8y=-6

Let's solve the second equation for 'x':



Subtract 8y to both sides:



Divide 3 to both sides:



Now let's plug this in for 'x' in the first equation:





Distribute:



Combine like terms:



Subtract 4 to both sides:



Divide 1/3 to both sides or multiply by its reciprocal, 3:



This is the y-value of our solution, we can plug it into any of the two equations to find the x-value:





Multiply:



Add 24 to both sides:



Divide 3 to both sides:



So our final solution is:
