Can x=4 in the expression 3(x-1)=20

if we take x=4 in the above expression we get,

3(4-1)=20

3×3=20

9≠20

so we can understand that x=4 is not the right value of x

hope it helps you

No

Step-by-step explanation:

We are given the equation:

3(x-1)=20

We want to know if x can equal 4. Therefore, we can substitute 4 in for x. If 4 is a solution, then both sides of the equation will be the same.

3(x-1)=20

x=4

3(4-1)=20

Solve inside the parentheses first. Subtract 1 from 4.

3(3)=20

Multiply 3 and 3

9=20

920

9 is not equal to 20. Therefore, 4 cannot be a solution.

21/58.
