The equivalent expression of 1/2 + 3c + 4/5 is \frac{13 + 15c}{10}

<h3 /><h3>How to determine the equivalent expression?</h3>

The expression is given as:

1/2 + 3c + 4/5

Take the LCM of the expression

\frac{5 + 15c + 8}{10}

Evaluate the like terms

\frac{13 + 15c}{10}

Hence, the equivalent expression of 1/2 + 3c + 4/5 is \frac{13 + 15c}{10}

Answer:

D:) (2,2,) is the Answer

Step-by-step explanation:

Solve the following system:


{X - 2 Y = -2 | (equation 1)


{3 X - 2 Y = 2 | (equation 2)



Swap equation 1 with equation 2:


{3 X - 2 Y = 2 | (equation 1)


{X - 2 Y = -2 | (equation 2)



Subtract 1/3 × (equation 1) from equation 2:


{3 X - 2 Y = 2 | (equation 1)


{0 X - (4 Y)/3 = (-8)/3 | (equation 2)



Multiply equation 2 by -3/4:


{3 X - 2 Y = 2 | (equation 1)


{0 X+Y = 2 | (equation 2)



Add 2 × (equation 2) to equation 1:


{3 X+0 Y = 6 | (equation 1)


{0 X+Y = 2 | (equation 2)



Divide equation 1 by 3:


{X+0 Y = 2 | (equation 1)


{0 X+Y = 2 | (equation 2)



Collect results:


Answer:  {X = 2 , Y = 2
