Solve y=3x-7 and 4x+3y=18 by substitution

x = 3

y = 2

Step-by-step explanation:

4x + 3(3x - 7) = 18 Substitute y

4x + 9x - 21 = 18 Simply

13x - 21 = 18 Add like terms

13x = 39 Add 21

x = 3 Divide by 13

y = 3(3) - 7 Substitute x

y = 9 - 7 Simply

y = 2 Subtract

Let's check:

4(3) + 3(2) = 18

12 + 6 = 18

18 = 18

It works!
