Linear System Solving using Substitution

Question

6x=3y+2

y-2x+4=0

Answer 1

When solving systems by substitution, it is best to choose an equation that has a variable without a coefficient, then solve for that variable. In this problem, the second equation has a y-term. If you solve that equation for y, then you can substitute that value of y into the first equation. I will leave that for you. Once you solve for y, you can then solve for x by plugging your solution for y into either equation.
