Answer:
A) x=5
B) x=4
Step-by-step explanation:
4x-3=2x+7
2x-3=7
2x=10
x=5
2x+6=7x-14
6=5x-14
20=5x
4=x
a) 4x - 3 = 2x + 7
=> 4x - 2x = 7 + 3
=> 2x = 10
[tex] = > x = \frac{10}{2} [/tex]
=> x = 5 (Ans)
b) 2x + 6 = 7x - 14
=> 6 + 14 = 7x - 2x
=> 20 = 5x
[tex] = > \frac{20}{5} = x[/tex]
=> 4 = x or x = 4 (Ans)
