Answer:
a) x = -10
b) x = 7
Step-by-step 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
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
