Answer:
<em>To solve system of equation by elimination, check if the values of x or y are lined up and have the same value.</em>
Or if the are not, take the numbers in x or y to multiply. Use the first to multiply the second equation and the second to multiply the first equation
<em>E</em><em>xample is, for the first step which is in italic form is</em>
<em> 2x + 3y =64...equation 1</em>
<em> 2x - 6y = 75...equation 2</em>
you can just eliminate for x by taking away equation 2 from equation 1
Or for step two which is in light form is
4x + 3y =64...equn 1
3x + 7y =80...equn2
to eliminate x, multiply equation 1 by 3 and equation 2 by 4
it will be 12x +12y =192
12x +28y =320
now you can solve.

ANSWER
EXPLANATION
We want to find the value of b in the following exponential equation.
Since the base on both sides of the equation are the same.
We equate the exponents to get,
We group like terms to obtain,
This will simplify to,
We now divide both sides by 2 to obtain,
