Please solve each algebraically : a) 5w= 30 b) 3x - 5 = 16 c) 10 - t = 17 d) n/5 = 18 e 4w -12 =2w + 3 THANK YOU!
alina1380 [7]

Answer:

w=6, x=7, t=7, n=90, w=15/2

Step-by-step explanation:

a) 5w = 30

30/5 = 6

w=6

b) 3x-5=16

Add 5 to each side.

3x+5=16+5

3x=21

21/3=7

x=7

c) 10-t=17

10-t=17

17-10-7

-t=-7

Negative and a negative is a positive.

t=7

d) n/5 = 18

n=18 * 5

n=90

e.) 4w-12=2w+3

4w=2w+3+12

4w=2w+15

4w−2w=15

2w=15

w= 15/2

What is the value of x in the equation: 5(6x - 4) = 20 + 4(3 + x)?
satela [25.4K]

Answer:

x = 2

Step-by-step explanation:

5 ( 6x - 4 ) = 20 + 4 ( 3 + x )

30x - 20 = 20 + 12 + 4x

30x - 20 = 32 + 4x

26x = 52

x = 2
