In order to use the elimination method<span>, you have to create variables that have the same coefficient—then you </span>can eliminate<span> them. Multiply the top </span>equation<span> by 5. Next add the </span>equations<span>, and </span>solve<span> for y. Substitute y = 10 into one of the original </span>equations<span> to find x.</span>
Answer:
x = 
Step-by-step explanation:
Given
+ 
= 5 ← combine terms on left side
= 5 ( multiply both sides by x )
8 = 5x ( divide both sides by 5 )
= x
X=6.2*20
X=124 MILES BETWEEN THESE 2 TOWNS.
Hope this helps you:)
Answer: x = -26
Step-by-step explanation:
3x-47
substitute x with 7: 3(7)-47
3(7) = 21 -47 = -26
