Question

3(4x-5)=45 show working
4^3x2^3=

Answer 1

3(4x - 5) = 45
first use the distributive property to clear the parenthesis
3*4x + 3*-5 = 45
12x - 15 = 45
add 15 to both sides
12x - 15 + 15 = 45 + 15
12x = 60
to clear the multiplication by 12, divide by sides by 12
12x/12 = 60/12
x = 5

4^3 * (x^2)^3
64 x^6

Answer 2

3 x 4x = 12x
3 x -5 = -15 12x - 15 = 45
+15 +15
12x = 60
divide by 12
x = 5
