We can use substitution or elimination Let’s use substitution Make slope intercept equation for the first equation Y = -x + 5 Now plug in the y value for the second equation -5x - 4(-x + 5) = -18 -5x + 4x - 20 = -18 -1x = 2, x = -2
Step-by-step explanation: The coefficient is the number that comes right before the variable. Another way to say this is it's what the variable is multiplied by.
