Answer:
x = 3
y = 2
Step-by-step explanation:
4x + 3(3x - 7) = 18 <em>Substitute</em><em> </em><em>y</em>
4x + 9x - 21 = 18 <em>Simply</em>
13x - 21 = 18 <em>Add</em><em> </em><em>like</em><em> </em><em>terms</em>
13x = 39 <em>Add</em><em> </em><em>2</em><em>1</em>
x = 3 <em>Divide</em><em> </em><em>by</em><em> </em><em>1</em><em>3</em>
y = 3(3) - 7 <em>Substitute</em><em> </em><em>x</em>
y = 9 - 7 <em>Simply</em>
y = 2 <em>Subtract</em>
Let's check:
4(3) + 3(2) = 18
12 + 6 = 18
18 = 18
It works!
