Question

Please help guys!!!!!!!!!!!!!!

Answer 1

a. 2(x+3)=x-4
2x+6=x-4
2x-x=-4-6 (collecting like terms)
x=-10

b. 4(5x-2)=2(9x+3)
20x-8=18x+6
20x-18x=6+8 (collecting like terms)
2x=14
x=7

Answer 2

a) x = -10

b) x = 7

Explanation:

a)

2(x + 3) = x - 4

2x + 6 = x - 4

2x - x = -4 - 6

x = -10

b)

4(5x - 2) = 2(9x + 3)

20x - 8 = 18x + 6

20x - 18x = 6 + 8

2x = 14

x = 7
