Simplify the equation -2x-3=4x-15

Mathematics
1 answer:
Reika [66]4 years ago
3 0
Add -2x to both sides to get 'x' on one side of the equation
-2x-3=4x-15
+2x   +2x
__________
-3=6x-15

add 15 to both sides to isolate 6x
-3=6x-15
+15=6x+15
__________
12=6x

divide both sides by 6 to get 'x' alone
12=6x
/6=/6
_____
2=x

so your answer is 2=x or you can flip it and it will be the same, x=2

exis [7]
To determine the lateral surface area of the rectangular prism, the equation would be, 
                        Lateral area = 2 x (HxL + HxW)
where H is height, L is length, and W is width. Substituting,
                    lateral area = 2 x (8x13.2 + 8x6) = 307.2 ft²
Martina's estimation is quite near to the calculated value which means that her estimation should have been really reasonable.
