The solution of the equation is  x=\frac{11}{7}

Step-by-step explanation:

To simplify an equation of x

  • Simplify each side of the equation
  • Collect x in side and the numerical terms in the other side
  • Find the value of x

∵ The equation is 2x + \frac{1-x}{4}=3

- Multiply all terms of the equation by 4 to cancel the denominator

 of the 2nd term in the left hand side

∵ The equation is 4(2x) +4 (\frac{1-x}{4})=4(3)

∴ 8x + (1 - x) = 12

∴ 8x + 1 - x = 12

- Add like terms

∴ (8x - x) + 1 = 12

∴ 7x + 1 = 12

- Subtract 1 from both sides

∴ 7x = 11

- Divide both sides by 7

∴ x=\frac{11}{7}

The solution of the equation is  x=\frac{11}{7}

Can someone help me do this
djyliett [7]

Answer:

See below

Step-by-step explanation:

It's hard to see your photo but if that say m∠T than your answer would be

m∠ L.

The drawings are saying the the triangles are congruent which means all the interior angles of one triangle are congruent to the angles of the second triangle.    m∠M = m∠J,   m∠K = m∠E and m∠L = m∠T

Since you have two of the angles, you can also determine what m∠L and m∠T is equal to.  The sum on all interior angles must be 180 degrees.

180 - 86 - 32 = 62
