Question

solve and check the equation 2x+18=40​

Answer 1

Answer:

Simplifying

2x + 18 = 40

Reorder the terms:

18 + 2x = 40

Solving

18 + 2x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-18' to each side of the equation.

18 + -18 + 2x = 40 + -18

Combine like terms: 18 + -18 = 0

0 + 2x = 40 + -18

2x = 40 + -18

Combine like terms: 40 + -18 = 22

2x = 22

Divide each side by '2'.

x = 11

Simplifying

x = 11

Answer 2

Answer:

answer is 11

Step-by-step explanation:

we know that =

L. H. S = R. H. S

2x + 18 = 40

18 move to R. H. S

2x = 40 - 18

2x = 22

now 2 move to R. H. S

x = 22 / 2

x = 11

CHECK

Let put 11 in place of x

2 ( 11 ) + 18 = 40

22 + 18 = 40

40 = 40
