Question

draw the following pair of linear equation in two variable and solve them 2x + Y - 7 equal to zero 4 x minus 3 + 1 equal to zero​

Answer 1

x = 2 ; y = 3

Step-by-step explanation:

Given: 2x + y - 7 = 0

4x - 3y + 1 = 0

Rearranging the equations, we get:

2x + y = 7 -----------------(1)

4x - 3y = -1-----------------(2)

(1) *3 --- 6x + 3y = 21

(2) ------ 4x - 3y = -1

Adding-- 10x = 20

So x = 20 / 10 = 2

Substituting x= 2 in (1), we get 2(2) + y = 7

4 + y = 7

y = 7-4

y = 3

Hence solved.
