Question

Solve for x :
i. 4x - 7 - (x+4) = 3x + 4 - (2x - 1)
ii. 17 ( 2 - x) - 5 ( x + 12 ) = 8

Answer 1

SoluTion:

(1) 4x - 7 - (x + 4) = 3x + 4 - (2x - 1)

→ 4x - 7 - x - 4 = 3x + 4 - 2x + 1

→ 4x - x - 3x + 2x = 4 + 1 + 7 + 4

→ 2x = 16

→ x = 16/2

→ x = 8

(2) 17 ( 2 - x) - 5 ( x + 12 ) = 8

→ 34 - 17x - 5x - 60 = 8

→ -22x + 34 - 60 = 8

→ -22x = 8 + 26

→ x = -32/22

→ x = -16/11

Answer 2

$\mathtt{\huge{\underline{\red{Question\:?}}}}$

Solve for x :-

i.) 4x - 7 - (x+4) = 3x + 4 - (2x - 1)

ii.) 17 ( 2 - x) - 5 ( x + 12 ) = 8

$\mathtt{\huge{\underline{\green{Answer:-}}}}$

➡i.) 8

ii.) -16/11

$\mathtt{\huge{\underline{\purple{Solution:-}}}}$

(i) 4x - 7 - (x + 4) = 3x + 4 - (2x - 1)

↗ 4x - 7 - x - 4 = 3x + 4 - 2x + 1

↗ 4x - x - 3x + 2x = 4 + 1 + 7 + 4

↗ 3x - 3x + 2x = 5 + 11

↗ 2x = 16

↗ x = 16/2

↗ x = 8

(ii) 17 ( 2 - x) - 5 ( x + 12 ) = 8

↗ 34 - 17x - 5x - 60 = 8

↗ -22x + 34 - 60 = 8

↗ -22x = 8 + 26

↗ x = -32/22

↗ x = -16/11
