Question

a) 7x + 13 – x = 2x + 29

b) (x2 + 1) . 3 = 102 + 52 . 2

c) 4 + √2× + 10 = 2^3
d) 6 . (m + 2) = 2 . (10 + m)



​

Answer 1

x + 13 - x = 2x + 29

13 = 2x + 29

13 -29 = 2x

-16 = 2x

-16/2 = x

- 8 = x

(x² + 1) . 3 = 102 + 52 . 2

3x² + 3 = 102 + 104

3x²  = 206 - 3

3x² =  203

x² = 203/3

√x² =  √203/3

x = ± √203/3

4 + √2× + 10 = 2³

 √2x + 14 = 8

√2x = 8 - 14

√2x = -6

(√2x)² = (-6)²

2x = 36

x = 36/2

x = 18

6.(m + 2) = 2 . (10 + m)

6m + 12 = 20 + 2m

6m - 2m = 20 - 12

4m = 8

m = 8/4

m = 2
