Answer:

x = 4

y = 3

Explanation:

Remark

If a triangle is equilateral all three sides are equal. So each side has equal statements.

Solution

3x + 2 = 5x - 2y Subtract 3x from both sides

2 = 5x -3x - 2y Combine

2 = 2x - 2y divide by 2

x - y = 1 Equation 1

3x + 2 = 6y - 4 Equilateral triangles have equal sides. Subtract 6y

3x - 6y + 2= - 4 Subtract 2

3x - 6y = -4 - 2

3x - 6y = - 6 Divide by 3

x - 2y = - 2 Equation 2.

Now subtract equation 1 from equation 2

x - 2y = - 2

x - y = 1 Subtract

- y = - 3 Multiply by -2

y = 3

Put y = 3 into equation 1

x - y = 1

x - 3 = 1 Add 3 to both sides.

x = 4

Answer

x = 4

y = 3
