Answer 1

answer : 7

explanation : given equation, 3x + 4 = 5(x - 2)

or, 3x + 4 = 5 × x - 5 × 2

or, 3x + 4 = 5x - 10

subtract 3x from both sides so you remove the variable term on left side.

i.e., 3x + 4 - 3x = 5x - 10 - 3x

or, (3x - 3x) + 4 = (5x - 3x) - 10

or, 0 + 4 = 2x - 10

or, 4 = 2x - 10

subtract 4 from both sides so you remove the constant term on left side.

or, 4 - 4 = 2x - 10 - 4

or, 0 = 2x - 14

now displace -14 from right to left with change their sign.

i.e., -(-14) = 2x

or, 14 = 2x

or, 2x = 14

or, 2x/2 = 14/2

or, x = 7

hence, value of x = 7

Answer 2

3x + 4 = 5(x - 2)

3x + 4 = 5x - 10

5x - 3x = 10 + 4

2x = 14

x = 14/7

x = 2

Hope it helps!!
