Question

4(x+3)-2(x-1) = 3x+3​

Answer 1

Answer:

X=11

Step-by-step explanation:

4x+12-2x+2=3x+3

2x+14=3x+3

14-3=x

x=11

Answer 2

Given:

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

What To Do:

We have to find the value of x.

Solution:

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

Solve the brackets in LHS,

⇒ 4x + 12 - 2x + 2 = 3x + 3

Rearrange the variables and constant,

⇒ 4x - 2x + 12 + 2 = 3x + 3

Solve them,

⇒ 2x + 14 = 3x + 3

Take 3 to LHS,

⇒ 2x + 14 - 3 = 3x

Take 2x to RHS,

⇒ 14 - 3 = 3x - 2x

Subtract 3 from 14,

⇒ 11 = 3x - 2x

Subtract 2x from 3x,

⇒ 11 = x

Verification:

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

Substitute the value,

⇒ 4(11 + 3) - 2(11 - 1) = 3 × 11 + 3

Solve the brackets,

⇒ 4 × 14 - 2 × 10 = 3 × 11 + 3

Solve the LHS,

⇒ 36 = 3 × 11 + 3

Solve the RHS,

⇒ 36 = 36

∴ LHS = RHS, hence, verified.

∴ Thus, x is 11.
