Question

What is x equal to ? 7x+3=2x-4

Answer 1

Step-by-step explanation

• Solve for x-term by making the x-term as the subject.

`7x +3 = 2x - 4 \\ 7x - 2x = - 4 - 3 \\ 5x = - 7 \\ x = ( - 7)/(5) \longrightarrow - (7)/(5)`

• Answer Check by substituting the value of x in the equation.

`7 ( - (7)/(5) )+ 3 = 2( - (7)/(5) ) - 4 \\ - (49)/(5) + 3 = - (14)/(5) - 4 \\ - (49)/(5) + (15)/(5) = - (14)/(5) - (20)/(5) \\ - (34)/(5) = - (34)/(5)`

The equation is true for the value of x. Therefore the answer is x = -7/5

Answer

`\large \boxed{x = - (7)/(5) }`
