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. WebStep 4: Plug in -4 (representing the space in between the points -3 and -5 on the number line) into the (x+3) (x+5) and solve. (-4+3) (-4+5)= -1 The answer is negative. Step 5: Look at x^2+8x+15<0. The answer is suppose to be LESS than 0, which means that the answer has to be a NEGATIVE number.
