Question

3x+4=5(x_2) solve the following equation​

Answer 1

Step-by-step explanation:

=> 3x+4 = 5x -10

=>3x -5x = -10 -4

=> -2x = -14

=> x = -14/-2

=> x = 7 .ans.

Answer 2

Answer:

7 hope you like have a nice day

Step-by-step 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

x = 7
