Question

7x+4=4x+7
please help lol

Answer 1

3x − 3 = 0

3(x − 1) = 0

x = 3 /3 = 1

Answer 2

Step-by-step explanation

• Given the equation.

`7x + 4 = 4x + 7`

• Solve for the value of x by making x as the subject of equation.

`7x - 4x = 7 - 4 \\ 3x = 3 \\ x = (3)/(3) \longrightarrow \frac{ \cancel{3}}{ \cancel{3}} = 1 \\ x = 1`

• Check the answer by substituting x = 1 in the equation.

`7(1) + 4 = 4(1) + 7 \\ 7 + 4 = 4 + 7 \\ 11 = 11 \longrightarrow \sf{true} \: \: \green{ \checkmark}`

Hence, the solution is x = 1.

Answer

`\large \boxed{x = 1}`
