Question

EXERCISE 6.2
1. Simplify and solve the following linear
equations.
A. 3 (x – 3) = 5 (2x + 1)
b. 10 (x – 5) -5 (x – 5) + 5 (x + 5) = 0
c. 3(5t-6) – 2(9t - 12) = 4(8t - 15) – 12
d. 0.25 (4y - 1) = 0.05 (10y - 1)
ve + x = -2

Answer 1

Answer:

A. 3x-9= 10x+5

grouping of like terms

10x-3x = -9-5

7x=-14

x=-2

B. 10x-50-5x+25+5x+25=0

grouping of like terms

10x-5x +5x -50+25+25

10x-10x-50+50

0

C. 15t-18-18t+24=32t-60-12

-3t +6=32t-72

6+72=32t+3t

78=35t

T= 78/35

D. 1y-0.25=0.5y-0.05

0.5y = 0.2

y=0.2/0.5
