Answer» Answer : x = 93 and y = 118 Step-by-step explanation : GIVEN linear equations, 4x - 3y - 18 = 0 4y - 5x - 7 = 0 ⇒ 4x - 3y - 18 = 0 4x - 3y = 18 ---[1] ⇒ 4y - 5x - 7 = 0 -5x + 4y = 7 ---[2] Multiply equation [1] by 4, 4(4x - 3y) = 4(18) 16x - 12Y = 72 ---[3] Multiply equation [2] by 3, 3(-5x + 4y) = 3(7) -15x + 12y = 21 ---[4] Add equations [3] and [4], 16x - 12y + (-15x + 12y) = 72 + 21 16x - 12y - 15x + 12y = 93 x = 93 Substitute x = 93 in equation [1], 4x - 3y = 18 4(93) - 3y = 18 372 - 3y = 18 3y = 372 - 18 3y = 354 y = 354/3 y = 118 Therefore, x = 93 and y = 118 Verification : x = 93 y = 118 [1] : 4x - 3y = 18 4(93) - 3(118) = 18 372 - 354 = 18 18 = 18 LHS = RHS [2] : 4y - 5x = 7 4(118) - 5(93) = 7 472 - 465 = 7 7 = 7 LHS = RHS Hence verified!

25.

4x - 3y - 18 = 0; 4y - 5x -7 = 0..solve the linear equation

Answer»

Answer :

x = 93 and y = 118

Step-by-step explanation :

GIVEN linear equations,

4x - 3y - 18 = 0
4y - 5x - 7 = 0

⇒ 4x - 3y - 18 = 0

4x - 3y = 18 ---[1]

⇒ 4y - 5x - 7 = 0

-5x + 4y = 7 ---[2]

Multiply equation [1] by 4,

4(4x - 3y) = 4(18)

16x - 12Y = 72 ---[3]

Multiply equation [2] by 3,

3(-5x + 4y) = 3(7)

-15x + 12y = 21 ---[4]

Add equations [3] and [4],

16x - 12y + (-15x + 12y) = 72 + 21

16x - 12y - 15x + 12y = 93

x = 93

Substitute x = 93 in equation [1],

4x - 3y = 18

4(93) - 3y = 18

372 - 3y = 18

3y = 372 - 18

3y = 354

y = 354/3

y = 118

Therefore, x = 93 and y = 118

Verification :

x = 93
y = 118

[1] : 4x - 3y = 18

4(93) - 3(118) = 18

372 - 354 = 18

18 = 18

LHS = RHS

[2] : 4y - 5x = 7

4(118) - 5(93) = 7

472 - 465 = 7

7 = 7

LHS = RHS

Hence verified!
