Question

EXERCISE 2.3 1. Solve the following equation (a) 4x = 3x + 7 (b) 5y - 3 = 3y - 5 (c) 42+3=6+22 (d) 2x - 1 = 14 - x (e) 5x + 9 = 5 + 3x 2x (f) 7x + 1 = + 3 15 (8) 2y+ 5 26 - y 3 3 (h) 8x + 4 = 3 (x - 1) + 7 6 (i) 4m = 7m - 7​

Answer 1

Answer:

a.) 4x=3x+7

4x-3x=7

x=7.

b.) 5y-3=3y-5

5y-3y=-5+3

2y=-2

y=-1.

d.)2x-1=14-x

3x=15

x=5.

e.)5x+9=5+3x2x

5x-6x=5-9

-1x=-4

x=4.

f.)7x+1=315

7x=314

x=44.8.

h.) 8x+4=3(x-1)+76

8x+4=3x-3+76

5x=69

x=13.8.

i.) 4m=7m-7

3m=7

m=7/3
