**Q) Solve the following pair of linear equations:**

**152x – 378y = – 74– 378 x + 152y = – 604**

**Ans: **

Given the equations:

Solve the following pair of linear equations:

152 x – 378 y = – 74 ….. (i)

– 378 x + 152 y = – 604 ….. (ii)

We need to first simplify the coefficients of variables x and y:

**Step 1: **Let’s add equation (i) and equation (ii) and we get:

……. (iii)

**Step 2: **Let’s subtract equation (ii) from equation (i) and we get:

……. (iv)

**Step 3:** Let’s add the equations (iii) and (iv) and we get:

**Step 4:** Let’s substitute x = 1, in equation (iii), we get:

**Therefore, **
