**Answer:**

y=3 x= -5/2

**Step-by-step explanation:**

simultaneous equations

2x + 4y = 7 ------ eq 1

-2x + 3y = 14 --------eq2

(different signs add)

(eq 2 + eq 1)

-2x +(-2x) = 0

4y+3y = 7y

7+14 = 21

7y= 21

(divide both sides by 7)

y= 21/7= 3

2x + 4(3) = 7

2x+ 12=7

2x = 7-12

2x = -5

x= -5/2

**Answer:**

34 degrees.

**Step-by-step explanation:**

Assuming AK is a straight line and being shown angle JDK is right and 90 degrees it can be stated that 4x + (3x-8) = 90 degrees.

Drop the parentheses and get 7x - 8 = 90.

Add 8 to both sides 7x = 98.

Divide both sides by 7, x = 14.

Plug that x value into (3x-8), [3(14)-8] = 34 degrees.

**The required expression is shown below **

**Step-by-step explanation:**

Consider the provided information.

Write an expression showing a ÷ 2 without the use of the division symbol.

Here the a ÷ 2 shows that the variable a is divided by 2.

**The model for this expression is shown in figure below:**

**We can rewrite the expression in fractional form as shown:**

If we write division expressions using the division symbol, we represent **dividend ÷ divisor.**

**In fractional form it will look like:**
