Answer:
i need the awnser too someone help
Step-by-step explanation:
Answer:
k = -2
Step-by-step explanation:
Divide 22 by -11 as well as -11k by -11
(You have to divide both sides by the number that k is to find your answer)
22 divided by -11 = -2
-11k divided by -11 = k
meaning you would get the answer of k = -2
Answer:
x=2
Step-by-step explanation:
2^2=4
2+2=4
X = -2 and y = -5
Explanation: Solve by using the process of elimination.
Step: Solve<span><span><span>−<span>1.5x</span></span>+<span>0.3y</span></span>=1.5
Solving for x = </span><span><span><span><span>−<span>1.5x</span></span>+<span>0.3y</span></span>+<span>−<span>0.3y</span></span></span>=<span>1.5+<span>−<span>0.3y *</span></span></span></span>Add -0.3y to both sides*
<span><span>−<span>1.5x</span></span>=<span><span>−<span>0.3y</span></span>+1.5
</span></span><span><span><span>−<span>1.5x</span></span><span>−1.5</span></span>=<span><span><span>−<span>0.3y</span></span>+1.5</span><span>−1.5 *</span></span></span>Divide both sides by -1.5*
<span>x=<span><span>0.2y</span>−1</span></span>
Step: Substitute <span><span>0.2y</span>−1 </span>for x in <span><span><span><span>1.8x</span>+<span>0.9y</span></span>=<span>−8.1</span></span>:
</span><span><span><span>1.8x</span>+<span>0.9y</span></span>=<span>−8.1
</span></span><span><span><span>1.8<span>(<span><span>0.2y</span>−1</span>)</span></span>+<span>0.9y</span></span>=<span>−8.1
</span></span><span><span><span>1.26y</span>−1.8</span>=<span>−8.1 *</span></span>Simplify both sides of the equation*
<span><span><span><span>1.26y</span>−1.8</span>+1.8</span>=<span><span>−8.1</span>+1.8</span></span>(Add 1.8 to both sides)
<span><span>1.26y</span>=<span>−6.3
</span></span><span><span><span>1.26y</span>1.26</span>=<span><span>−6.3</span>1.26 *</span></span>Divide both sides by 1.26*
<span>y=<span>−5
</span></span>Step: Substitute <span>−5 </span>for yi n <span><span>x=<span><span>0.2y</span>−1</span></span>:
</span><span>x=<span><span>0.2y</span>−1
</span></span><span>x=<span><span><span>(0.2)</span><span>(<span>−5</span>)</span></span>−1
</span></span><span>x=<span>−2 *</span></span><span>Simplify both sides of the equation*</span>
