Answer:

Step-by-step explanation:

a)1) As denominators are same, keep the same denominator for the result also

Add the numerators and write the new numerator.

$\frac{3y}{4}+\frac{5y}{4}=\frac{3y+5y}{4}=\frac{8y}{4}$ = 2y

20 Reduce to simplest form by dividing the numerator and denominator by GCF

x = 3

2x + y - z = 3 → (1)

- x + y + 2z = 0 → (2)

3x + 2y + z = 9 → (3)

we require to eliminate the y and z terms from the equations

(1) + (3) : 5x + 3y = 12 → (4)

multiply (1) by 2

4x +2y - 2z = 6 → (5)

(2) + (5) : 3x + 3y = 6 → (6)

(4) - (6) : 2x = 6 ⇒ x = 3
