Solve by using substitution
WebAnd we have a system of equations here. The first equation is 2y is equal to x plus 7. And the second equation here is x is equal to y minus 4. So what we want to do, when they say substitution, what we want to do is substitute one of the variables with an expression so that we have an equation and only one variable. WebSo, first of all we want to know when the two lines have the same slope, which means we want to solve the equation. −3∕𝑚 = − (𝑚 + 2)∕5. Multiplying both sides by (−5𝑚) we get. 15 = 𝑚 (𝑚 + …
