63+12x<15
12x<-48 (subtract 63 from both sides)
x<-4 (divide out the 12)

X > -4

63 + 12x < 15
1st. We will subtract 63 on both sides, to leave 12x on one side by itself:
63 - (63) + 12x < 15 - (63) =
12x < -48

2nd: Then we divided by 12 on both sides to isolate x, or to leave x by itself.
12x /12 < -48 /12=
x>-4

*Remeber, make sure to switch the signs from less than x to greater than x. We do that because we are either dividing or multiplying by a negative number!

Solve the equation. \dfrac32 + b = \dfrac74 2 3 ​ +b= 4 7 ​ start fraction, 3, divided by, 2, end fraction, plus, b, equals, sta
Xelga [282]

Given:

The equation is

\dfrac{3}{2}+b=\dfrac{7}{4}

To find:

The value of b.

Solution:

We have,

\dfrac{3}{2}+b=\dfrac{7}{4}

Subtracting both sides by \dfrac{3}{2}, we get

b=\dfrac{7}{4}-\dfrac{3}{2}

b=\dfrac{7-2(3)}{4}

b=\dfrac{7-6}{4}

b=\dfrac{1}{4}

Therefore, the value of b is \dfrac{1}{4}.
