Answer 1

Answer:

x = .8

y = 2.2

Step-by-step explanation:

We can solve by substituting y = 1.5x + 1 into the first equation!

$(1.5x+1) + x = 3\\1.5x +x=2\\3x+2x=4\\5x=4\\x=\frac{4}{5}!$

Next, we need to substitute the value of 4-fifths into an equation! I will choose the second equation!

$\frac{3}{2} (\frac{4}{5}) + 1\\\\\frac{6}{5}+1\\=\frac{11}{5} !$

When converted into decimal form, y and x should look like this:

4/5 = .8

11/5 = 2.2
