x=6

Answer 2

Answer:

6

Step-by-step explanation:

3x - 11 = 7

we are moving the 11 over to the other side. as of general knowledge, when a  negative figure goes across the = sign,the number becomes +.

So we are grouping all like terms getting ready for the division process.

3x       = 7 + 11

3x       = 18

to find x, both sides of the equation must be divided by the co-effecient of x. that is 3

3x/3    = 18/3

the 3 divides 3 leaving 1. since 1x i not written it becomes just x. 3 divides 18 leaving 6

∴x          = 6
