Question

Pls help this is due tmrw and i actually suck at math

Solve the following system of equations using substitution. Show ALL of your work and write the ordered pair in the space provided. y = x - 1 y = 2x + 1

Answer 1

substitution method would go as follows

5x-2=7x-8 we than rearange it so it becomes 5x-7x=-8-2 this than becomes -2x=-6 so x=3

we can than substitute 3 for x in one of the first equations

y=7 times 3-8 = 21-8 = 13

so therfore the interception should be at 3,13
