Mlachi is wrong 1/3 times -30 = 10 not 30
<em>Answer:</em>
<em>In my opinion the answer is </em><em><u>y = 6</u></em>
<em>Step-by-step explanation:</em>
<em>We have two unknowns from the equation therefore, two equations are needed. These equations are:
</em>
<em>
</em>
<em>3x + y = 9 </em>
<em>y = –4x +10 </em>
<em>
</em>
<em>To solve for y, we first substitute the second equation to the first one.
</em>
<em>3x + –4x +10= 9 </em>
<em>x = 1
</em>
<em>
</em>
<em>We substitute the value of x to either of the equations and solve for y.
</em>
<em>
</em>
<em>y = –4(1) +10 </em>
<em>y = 6</em>
If you are asking how to write one, this would be an example.
You have the expression: 7r + 8r +2
r(7+8)+2 would be how you would write it, but as I asked for more details, I want to know if you have a specific expression to use for that.
Answer:
79
Step-by-step explanation:
