Question

2x + 3y = 8
4x + 2y = 8​
sove by substitution ​

Answer 1

Answer:

x = -2 ; y = 4

Step-by-step explanation:

2x + 3y = 8 -------(i)

4x + 2y = 8 -------(ii)

From Equation (i) we get,

2x = 8 - 3y

x = $\frac{8-3y}{2\\}$

Substituting the value of x in equation (ii),

4($\frac{8-2y}{2\\}$) + 2y = 8

16 - 4y + 2y = 8

-2y = -8

y = 4

Substituting the value of y in eqation (i)

2x + 3(4) = 8

2x = -4

x = -2

Answer 2

Answer:

x=1, y=2

Step-by-step explanation:

(2x + 3y =8) × 4

(4x + 2y= 8) × 2

8x + 12y = 32

8x + 4y = 16

By subtracting that we got

y= 2

then substitute the value of y in any equation,

we got x=1
