Question

a) Evaluate : 2a + 3b - c , if a = 2 , b = 3 and c = 10
b) If 4p -3 = 17 , find p
c) Find x if, 6x + 10 = 34

Answer 1

Step-by-step explanation:

(a) Given,

2a+3b-c eq(1)

(a=2 , b=3 , c=10)

substitute the given values in the eq(1)

2(2)+3(3)-10

4+9-10

13-10

3

(b)Given,

4p-3 = 17

4p = 17+3

4p = 20

p = 5

(c) Given,

6x+10 = 34

6x = 34-10

6x = 24

x = 4

Answer 2

Answer:

a) 3, b)7/2, c)4

Step-by-step explanation:

here,

a=2

b=3

c=10

2a+3b-c

2×2+3×3-10

4+9-10

=3

b) 4p-3=17

4p=17-3

p=14/4

p= 7/2

c) 6x+10=34

6x=34-10

x=24/6

x=4
