6x=12

x=12/6

x=6

Answer 2

Answer:

Given:-

Simplify: 6x - 5 = 7.

To Find:-

The value of "x".

Note:-

●》To find some variables, we need to rearrange a term from its side to another and that signs are also changed. For example - negative becomes positive, multiple becomes divisional.

●》Left hand side sums = Right hand side.

Solution:-

☆ Equation~

▪︎$6x - 5 = 7$

☆ According to note first point ( rearrangement )~

▪︎$6x = 7 + 5$

▪︎$6x = 12$

▪︎$x = \frac{12}{6}$

☆ After doing calculations~

▪︎$x = 2$

x = 2

Checking:-

♤ According to note second point ( L.H.S = R.H.S ), Let's check~

• $6x - 5 = 7 \ \ ?$

♤ Applying the value~

• $6 × 2 - 5 = 7 \ \ ?$

• $12 - 5 = 7 \ \ ?$

• $7 = 7 \ \ ?$

♤ Yes!

Hence, proved that x = 2.

Answer:-

Hence, the value of x = 2.
