Please help me with this problem! i need it answered asap! (will give brainliest)

Use substitution to solve the system of equations.
y + x = 3
y = 1.5x + 1

x = .8

y = 2.2

Step-by-step explanation:

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

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

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

4/5 = .8

11/5 = 2.2

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
