Use the equation to complete an algebraic proof that proves the answer is x = 7/6. Write your proof in your journal and upload y
Ivahew [28]

Answer:

x=7/6

Step-by-step explanation:

subtract the 4x from both sides of the equation

(2x+6)-4x=4x-3-4x

find common denominator

(2x+6)/5+(5(-4)x)/5=4x-3-4x

then combine fractions

(2x+6+5(-4)x)/5=4x-3-4x

then multiply the 5&4

(2x+6-20x)/5= 4x3-4x

combine terms

(-18x+6)/5= -3

then multiply everything by 5

-18x+6= -15

subtract the 6 from both sides

-18x= -21

divide -21 by -18

(-21)/(-18)=x

find greatest common multiple (3) and solve

x = 7/6

Determine the type and number of solutions of 4x^2-5x+1=0.
Arlecino [84]
<span>4x² - 5x + 1 = 0
a = 4; b = - 5, c = 1
</span>Δ = b² - 4.a.c
Δ = (-5)² - 4.4.1
Δ = 25 - 16
Δ = 9
<span>
x = - b </span>± √Δ / 2.a
x =  \frac{-5\± \sqrt{9} }{2*4}
x =  \frac{-5\±3}{8}
x' =  \frac{-5-3}{8} =  \frac{-8}{8} = -1
x' = \frac{-5+3}{8} = \frac{-2}{8} (\div2) = \frac{-1}{4}


A. Two real solutions (x' = -1 and x'' = -1/4)
