Answer:
The second one
Step-by-step explanation:
Answer:
x=-2
Step-by-step explanation:
5x -10x- 30= 10x
-5x -30 = 10x
-30=15x
x=-2
So, this is how we do it O w O<span><span>x = <span>−1</span></span>;<span>y = <span><span>3x</span>+1</span></span></span>Step: Solve <span>x = <span>−1 </span></span>for x:Step: Substitute <span>−1 </span>for x in <span><span>y = <span><span>3x</span>+1</span></span>:</span><span>y = <span><span>3x</span>+1</span></span><span>y = <span><span><span>(3)</span><span>(<span>−1</span>)</span></span>+1</span></span><span>y = <span>−2</span></span>(Simplify both sides of the equation)Answer:<span><span>x=<span>−<span><span>1<span> and </span></span>y</span></span></span>=<span>−<span>2
Hope I helped! :3</span></span></span>
