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. WebHow do I make x the subject of the formula y = 2x - 3? You need to solve the equation for x. 1. Add 3 to both sides, giving y + 3 = 2x. 2. Divide both sides by 2, giving y/2 + 3/2 = x.

First we must isolate the 2y/5. To do this we can add 3x to both sides to get rid of it on the left side and get 2y/5 on its own. This gives us: 2y/5 = 2 + 3x. Now, the 2y is divided by 5, therefore by doing the inverse function of division which is multiplication, we can get 2y on its own. razor\\u0027s edge lisbon nd
