<u>Answer:</u>
<em>Equation is 4x-6(6x-1) = -11
</em>
<u>Step-by-step explanation:</u>
<em>The set of equations given are
</em>
<em>6x-y=1
</em>
<em>4x-3y=-11
</em>
A pair of linear equations in <em>two variables x and y is given</em> in the set of equations. If there are two variables we require two equations to find the <em>value of variables</em>. Substitution is one among the methods used to solve pair of linear equations in two variables.
Here we have to <em>determine the value of y</em> from the first equation and then substitute it in the second equation.
<em>6x-y=1
</em>
<em>y=6x-1
</em>
<em>Substituting this value in second equation 4x-6y=-11 </em>
<em>we get </em>
<em>4x-6(6x-1) = -11
</em>
Answer:
D
Step-by-step explanation:
a^2 cancels out a^5 remaining a^3 denominator
b2 cancels b4 = b2 numerator
c3 cancels out c8 = c5 remaining denominator
36/4 = 9
therefore 9b^2 /a^3 c^5
Answer:
750 miles
Step-by-step explanation:
Given
Required
Determine the number of miles
Represent the number of miles with m
So, we have:
Collect Like Terms
Solve for m
<em>Hence, I travelled 750 miles</em>
Answer:
x-30
Step-by-step explanation:
Firstly, you do the first step, which is, 3x-18+4x+12-6x, then you continue simplifying it: 7x-18+12-6x.
Keep it on and on, the next step: x-18+12, add 18 and 12 together you get 30.
So the final answer is x-30
