Answer: 5
Step-by-step explanation:
It is hard to show work for this problem because it very similar to a basic addition or subtraction problem.
Just so you have the answer and how to solve. -27 is the answer. Think about it like 41-14 then add the negative back. But I would strongly suggest not writing that as work because you teacher might get confused about what you are doing
Hello.
For the first one its
<span>x = -0.2 + -0.4y
</span>Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation
.
5x + 2y + -2y = -1 + -2y
Combine like terms: 2y + -2y = 0
5x + 0 = -1 + -2y
5x = -1 + -2y
Divide each side by '5'.
x = -0.2 + -0.4y
For the second its
<span>x=<span><span>−y</span>+2</span></span>
Step 1: Flip the equation.<span><span><span>−x</span>+2</span>=y
</span>Step 2: Add -2 to both sides.<span><span><span><span>−x</span>+2</span>+<span>−2</span></span>=<span>y+<span>−2</span></span></span><span><span>−x</span>=<span>y−2
</span></span>Step 3: Divide both sides by -1.<span><span><span>−x</span><span>−1</span></span>=<span><span>y−2</span><span>−1</span></span></span><span>x=<span><span>−y</span>+2</span></span>
Have a nice day
