Have you used PEMDAS if not the abbreviation stands for Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. So you start with 3² = 3x3 = 9 now 5x6=30 so now you have a equation of (4 + 7 x 9 - 30) = 4 + 63 - 30 = 67 - 30 = 37 I hope I helped!!!!

Answer:

$x>\frac{7}{2}$

Step-by-step explanation:

2x - 3 > 4

Add 3 to both sides.

2x - 3 + 3 > 4 + 3

Simplify.

2x > 7

Divide both sides by 2.

$\frac{2x}{2} >\frac{7}{2}$

Simplify.

$x>\frac{7}{2}$
