Solution by Steps
step 1
Combine like terms on the left side of the inequality: 4x3+6x>5x+74x - 3 + 6x > 5x + 7 becomes 10x3>5x+710x - 3 > 5x + 7
step 2
Subtract 5x5x from both sides to isolate the variable term on one side: 10x5x3>710x - 5x - 3 > 7 simplifies to 5x3>75x - 3 > 7
step 3
Add 3 to both sides to further isolate the variable term: 5x3+3>7+35x - 3 + 3 > 7 + 3 simplifies to 5x>105x > 10
step 4
Divide both sides by 5 to solve for xx: 5x5>105\frac{5x}{5} > \frac{10}{5} simplifies to x>2x > 2
Answer
x>2x > 2
